Samsung Rapid SSD. Samsung SSD 840 Evo

Samsung SSD 840 Evo

Solid State Drives (SSD) are one of the most exciting technological developments to happen in workstations for some years. The drives are lightning fast, incredibly responsive and can make a huge difference to any machine, old or new (see our SSDs for CAD article).

But world domination of these drives, which use NAND-based flash memory instead of rotating platters, is still some way off. Capacities need to increase and need to drop before SSDs completely take over from traditional Hard Disk Drives (HDDs).

Until recently SSDs plateaued at 500GB — plenty of storage for entry-level CAD use but not really enough when large CAD/BIM datasets start stacking up. In contrast HDDs go up to 4TB and win hands down on price. A typical HDD costs £0.04 per GB whereas an SSD might be anywhere from £0.50 to £0.80.

That is a big premium to pay and another reason why SSDs are commonly found alongside HDDs inside desktop workstations. SSDs deliver incredible performance for operating system, apps and current datasets, while the HDD is used to store the bulk of the data.

The good news is the technology is moving incredibly fast.

In just a few years Samsung has established itself as one of the world’s leading SSD manufacturers. Unlike its competitors, the South Korean giant manufactures virtually every component of its SSDs (from the NAND flash memory to the memory controller). This not only helps it bring new products to market faster but also price them aggressively.

The new Samsung SSD 840 EVO is a case in point. It is not only the first true 1TB SSD for mainstream use, but it comes in at an incredible price — £0.43 per GB. This may still be ten times the cost of a typical HDD but, considering the technology on offer, it is market leading.

A class divide?

As the name suggests Samsung’s SSD 840 EVO is an evolution of the Samsung SSD 840 that launched in 2012. It offers the same three-year warranty but delivers bigger capacities, better performance and includes some Smart features designed to boost read / write speeds in certain scenarios.

Like most modern SSDs the 840 EVO uses the SATA 3.0 (6Gb / 600GB/s) interface. It will also work on SATA 2.0 (3Gb / 300GB/s) and SATA 1.0 (1.5Gb / 150GB/s), so is compatible with older workstations, but its speed will be throttled.

There is a choice of five capacities: 120GB, 250GB, 500GB, 750GB and 1TB so there is something for pretty much everyone. Read performance is virtually standard across the range but write speed tails off with the lower capacity drives, though much less so than it does in the original SSD 840 drives.

The 840 EVO is positioned as a consumer drive for client PCs, meaning the Samsung 840 PRO will continue to FOCUS on professional users.

The 840 PRO promises better reliability (backed by a five-year warranty) and faster consistent performance, particularly with large datasets, both of which are attractive to workstation users. However, this does not mean the 840 EVO is not suitable for CAD / BIM workstations.

On the desktop there is plenty of scope for entry-level workstations where cost is critical. At £73 (ex VAT) the 120GB SSD EVO is an extremely cost effective way to boost system performance, partnering with a traditional 1TB HDD to store data.

For those that want to load and save large CAD datasets at lightning quick speeds, it is an interesting alternative to a slower HDD in a traditional SSD / HDD setup. Here a 500GB, 750GB or 1TB 840 EVO could be used for data, while a 128GB or 256GB 840 PRO does the more demanding work for operating system and applications.

The 840 EVO is also likely to appeal to mobile users where fast, high capacity storage is of paramount importance. A lot of mobile workstations only support a single drive so users traditionally have to choose between capacity (HDD) or performance (SSD). A 750GB or 1TB EVO 840 could offer both.

Performance

On paper there is very little difference between the 840 EVO and the 840 PRO, which we reviewed back in March 2013 (see tinyurl.com/AECSSD).

This was confirmed when we put both drives through their paces in a Dell Precision T1700 workstation (see page 33). Our ‘Pack and Go’ test, which reads / writes CAD parts at the same time, and the widely used AS-SSD benchmark, which tests for sustained and random read/write performance, both delivered virtually identical scores.

PCI Express the future of high-speed storage

The SATA 3.0 interface was launched in 2009 but few would have predicted that we would already be hitting the limits.

The fact is many drives have pretty much saturated the 6Gb (600MB/s) available in sustained read / writes. The real innovation in SSDs is currently coming from improvements in random read / write performance.

Samsung is already waiting for the next standard to arrive. SATA Express, which should appear commercially in 2014, will make use of PCI Express (PCIe), the same interface used for high-speed 3D graphics.

Interface speeds may increase to 8Gb/s or 16Gb/s and future motherboards will offer slots for SATA Express and traditional SATA. SATA Express will be backward compatible with the standard SATA 3.0 interface.

When pushing the drive to its limits, however, particularly when working with large CAD models, some users may start to see the limitations of Samsung’s so-called consumer drive.

Samsung SSD 870 EVO. Лучший SSD для народа

The 840 PRO’s fast read and write performance is largely down to the type of NAND flash memory it uses (2-bit MLC). The EVO 840, on the other hand, uses slower memory (3-bit MLC) so it owes its fast write speeds to ‘TurboWrite’ a new technology that temporarily writes data to a high performance buffer. Then, when the drive is idle, the buffer gets flushed into the main 3-bit MLC storage freeing up space for the next write.

The size of the buffer varies according to the capacity of the drive — 120GB drive (3GB buffer), 250GB (3GB), 500GB (6GB), 750GB (9GB) and 1TB (12GB).

If the buffer becomes full, any outstanding data will be written straight to the main MLC storage, which is significantly slower.

While the 1TB drive should be able to handle some pretty sizeable CAD / BIM datasets without saturating the buffer, the 120GB and 250GB drives will fill up a lot quicker.

This is an important consideration when selecting the size of your drive, as is the fact that the 120GB and 250GB drives deliver slower random write performance (see chart above). This may also point you more towards the slightly more expensive 840 PRO, which will deliver fast, sustained write speeds all of the time.

The 840 EVO has another trick up its sleeve with ‘Rapid’, a software mode that can be toggled on and off within Samsung’s bundled Magician software.

Rapid mode (Real-time Accelerated Processing of I/O Data) aims to boost performance by using the workstation’s system memory (rather than the SSD) to serve up frequently used data.

The software continually analyses the application and data usage and caches the most frequently used files into DRAM (1GB max). Then, when this data is needed, it can be retrieved much quicker than would have been possible over the SATA 3.0 interface. The ‘cache map’ that builds up over time is stored permanently on the SSD so it can be recalled between reboots.

Rapid mode sounds great in theory, and our AS-SSD benchmark results show some incredible increases in performance in both read and write speeds, more than twice as fast in some instances. But results are inconsistent (though always fast) and it should not be forgotten that AS-SSD is a synthetic benchmark. Long term testing is the only real way to ascertain exactly how useful it is.

Rapid mode is not exclusive to the Samsung 840 EVO SSD. It will also be supported in the Samsung 840 PRO SSD.

Magic trick

Samsung’s Magician Software is a free tool bundled with Samsung SSDs. It performs a number of roles, ranging from performance optimisation and drive health monitoring to firmware updates and secure erase.

The software is very easy to use. Simply choose one of three profiles: Maximum Performance, Maximum Capacity or Maximum Reliability and the software will fine tune Windows accordingly. Users can also dive in and manually customise features of the OS.

Magician also gives a running analysis of drive health, showing how many bytes have been written over the lifetime of the drive and warning the user in advance when the drive might need to be replaced. And, of course, there is Rapid Mode, which we just covered in the previous section.

Conclusion

The 840 EVO is an impressive addition to Samsung’s hugely-respected family of SSDs. It delivers exceptional performance and has the potential to give any HDD-based workstation a completely new lease of life. And with the bundled Migration software the transition can be completely painless.

The EVO might not have the same workstation-class credentials afforded to its sibling, the 840 PRO, but it wins hands down on capacity and price per GB. And for these reasons alone it should still be considered for design and engineering — as a companion drive to an 840 PRO or going it alone in a budget or mobile workstation.

Upgrade your HDD in minutes

To clone a disc simply connect the target disc (Samsung SSD) via SATA or USB and Samsung’s Data Migration software then checks for space. If the target disc has enough space for all of the source files cloning can start immediately. A 500GB SATA SSD can be cloned in as little as 10 minutes

Upgrading your HDD to a Samsung SSD is incredibly easy and can be done in as little as 10 minutes depending on the size of your data and the speed of your hardware.

All drives come with Samsung’s easy to use Data Migration software, which creates an exact clone of your current drive in a few easy steps. Once the clone is complete you simply pop in the new drive, boot into Windows and away you go. Your workstation will look exactly the same but it should feel a whole lot quicker.

There are some caveats to this. If a file is in use it will not be copied. For example, we found that our Outlook OST file did not copy across in the cloning process.

Also, if your target drive does not have enough capacity to copy all of your source files a ‘Custom Cloning’ option can be used to exclude large media files and automatically copy them to an external drive. This is great if you just want to grab your entire collection of AVI or MP3 files, but unfortunately there is no way to customise the software so it excludes entire folders or large CAD or BIM files.

We would recommend a bit a housekeeping first — manually move your data files to a USB or network drive until you have freed up enough space for a straightforward clone.

Cloning can be done via SATA or USB. SATA 3.0 is quickest, but you will need a spare SATA port and power cable inside your machine. USB 3.0 is also quick but USB 2.0 can take a few hours.

Samsung offers two optional upgrade kits, which provide all the hardware you will need for the swap. Each kit adds around £10 onto the cost of a standard drive.

The desktop kit includes a SATA data cable, a slow USB 2.0 to SATA connector and a 3.5-inch bracket with screws, which converts the 2.5-inch drive so it can fit into a standard desktop chassis.

The laptop kit includes a fast USB 3.0 to SATA connector and a mounting spacer bar, which adds more thickness to the 6.8mm drive so it can fit snuggly into the laptop’s drive bay.

Samsung SSD 850 Pro review: Top-notch solid-state drive for a premium price

The Samsung SSD 850 Pro is the first solid-state drive on the market that uses the new 3D, vertical NAND flash memory to offer ultra-high endurance, top performance, a great set of features and the all-new 2TB capacity.

samsung, rapid

CNET editor Dong Ngo has been involved with technology since 2000, starting with testing gadgets and writing code for CNET Labs’ benchmarks. He now manages CNET San Francisco Labs, reviews 3D printers, networking/storage devices, and also writes about other topics from online security to new gadgets and how technology impacts the life of people around the world.

Editors’ note: The review was updated on July 6, 2015, when the new 2TB version was released.

Samsung SSD 850 Pro

The Good

The Samsung SSD 850 Pro has fast performance, high endurance.- you can write a lot of data to it before it becomes unreliable.- and its 2TB capacity is the highest on the market. The drive comes with a lot of useful features, including encryption, and a great performance-boosting mode called Rapid.

The Bad

The drive is expensive compared with competing solid-state drives. The Samsung Magician software only works with Windows.

The Bottom Line

The Samsung SSD 850 Pro is one of the best standard consumer-grade solid-state drives on the market, but there are cheaper alternatives with similar performance.

There are plenty of reasons to be excited about the Samsung SSD 850 Pro.

It’s the first SSD on the market that uses the innovative 3D vertical NAND (V-NAND) flash memory for top performance and ultra-high endurance. It comes with a rarely seen 10-year warranty and, among other features, has a Rapid mode that further boosts its performance. What’s more, it’s one of the first drives available in the all-new 2TB capacity, along with its sibling the SSD 850 Evo.

Naturally, though, all of that comes at a price. Depending on the capacities, the new Samsung drive is one of the most expensive among standard SSDs, currently costing 98, 152, 255, 489 and 1,000 for 128GB, 256GB, 512GB, 1TB and 2TB respectively. (That’s about £63 to £640 and AU128 to AU1,310 converted.) Note that the pricing for the newly released 2TB version is the suggested retail price, and its street price will likely be lower.

If you don’t mind paying the premium, the Samsung delivers the best performance, highest capacity and longest warranty time currently available on the market. It’s especially great for those who regularly need to write a huge amount of data to the internal drive every day. But if you’re on stricter budget, the 850 Evo is cheaper, with comparable performance in many tests.

For more options on great internal drives, check out this list of top SSDs on the market.

3D memory cell strings, ultra-high endurance

The Samsung SSD 850 Pro is a standard internal drive that supports the latest SATA 3 (6Gbps) standard and will work in any instance where a regular SATA hard drive is used. Similar to most SSDs, it’s 7mm thick. Like most standard drives, it’s a square device that’s 2.5 inches diagonally, with the standard SATA port on one of its sides. The new drive looks exactly the same as the previous 840 Pro model.

On the inside, however, the new drive is the first that brings 3D vertical NAND flash memory to SSDs, called Samsung second-gen 86-gigabit 40nm MLC V-NAND.

Traditionally, NAND flash memory cells.- the storage units on an SSD.- are placed flat on the surface of the silicon wafer, limiting the number of cells you can cram into a square inch. In the case of the Samsung drive, cells are also stacked up to 32 layers. This allows for packing significantly more memory cells in the same amount of wafer bits, which greatly increases the density. That plus Samsung’s customized firmware and the improved MEX controller, allow the drive to also offer great performance and ultra-high endurance.

Endurance is the number of program-erase (P/E) cycles an SSD has before you can’t write onto it any more.- read more about SSD endurance here. Samsung says you can write at least 150TB (on the 128GB and 256GB capacities) or 300TB (on the 512GB, 1TB and 2TB capacities) of data to the 850 Pro before it runs out of P/E cycles, almost twice that of the SanDisk Extreme Pro, which has an endurance of 80TB. This means most of us won’t use up the drive’s endurance in our lifetime.

Premium pricing

Apart from the 2TB, which just came out and has the suggested price of 1,000, the US street of the other capacities are at 98, 152, 255, 489 for 128GB, 256GB, 512GB and 1TB respectively. Generally, the drive costs from 47 cents to 59 cents per gigabyte, among the most expensive on the market. The SSD 850 Evo for example, costs just around 33 cents per gigabyte. Note that when buying SSDs, the higher the capacity, the less cost per gigabyte. This means buying larger capacity drives will give always you more for your money.

It’s important to note that while the the SSD 850 Pro is faster than the SSD 850 Evo for the most part, in real-world usage, you might not notice at all. The SSD 850 Pro’s 10-year warranty, however, is clearly better than the five-year of its sibling.

Top performance

The Samsung SSD 850 Pro did very well in testing. I tested the new drive with its 256GB, 512GB, 1TB and the new 2TB capacities and they basically offer the same performance. The drives were tested as a main storage device that host the operating system, since the Rapid mode doesn’t work when the drive is used as a secondary drive. The test machine is a midrange computer running a Core i5 processor with 8GB of system memory.

In our sequential data transferring test, the new drive scored a sustained speed of 246MBps when doing both writing and reading at the same time, slightly slower than the 251MBps of the SanDisk Extreme Pro. When Rapid mode is turned on, however, the Samsung registered 287MBps, by far the fastest result.

In all the Samsung 850 Pro is one of the fastest, if not the fastest SSD on the market. Note that you need to use it in a computer that supports SATA 3 (6Gbps) to be able to fully appreciate its performance.

Conclusion

If money is not an issue, you can’t go wrong with the Samsung SSD 850 Pro. The drive has it it all: top performance, plenty of useful features, the highest storage capacity (up to 2TB) and a super long 10-year warranty.

But cost is always an issue and in real-world usage, chances are you won’t notice the little extra performance the 850 Pro has over competing drives that are cheaper, such as its sibling SSD 850 Evo that costs some 20 percent less and offers neck-and-neck performance in many tests.

Generally SSDs are all so much faster than regular hard drives that the performance gaps between them are minimal to the user. So while the SSD 850 Pro is a great drive, worthy of the investment for professional users, it does not offer the most for your money.

At the end of the day, if the best deal is what you’re after, the 850 Evo is the way to go, but if you want something top-notch without any compromises, the 850 Pro is the drive you want.

Samsung SSD 990 Pro: The Latest V-NAND And A New 8nm Controller Boost Performance

A new, more efficient controller and fresh V-NAND boost Samsung SSD 990 Pro series performance to over 7.4GB/s, while consuming less power. It’s a win-win.

  • Excellent Sequentials
  • Top-Notch PCMark Score
  • Cool, Low-Power 8nm Controller
  • Better At Low Queue Depths

The Samsung SSD 990 Pro remains tied to the PCIe Gen 4 interface, but this drive features an updated controller and Samsung’s latest V-NAND flash memory to boost performance significantly. You can take a look at the Samsung SSD 990 Pro’s main features and specifications here, but we’ll dig in much further in the pages ahead.

Samsung SSD 990 Pro Specifications And Features

Samsung SSD 990 Pro Drives With Heatsinks Are Coming Soon

Samsung SSD 990 Pro Gen 4 drives will initially be offered in two capacities—1TB and 2TB—and in two flavors, with and without an integrated heatsink. A 4TB model is also planned, but won’t be arriving until next year. We will be featuring the 2TB model without heatsink in this evaluation.

All of the drives in the Samsung SSD 990 Pro series use the common M.2 (2280) ‘gumstick’ form factor, but the performance between the different models varies slightly depending on their capacity. Both capacities will offer similar sequential transfers, of 7.45GB/s (read) and 6.9GB/s (writes), and similar IOPs at QD1 (Queue Depth), but at QD32 the 1TB model will have somewhat lower (but still good) random read performance.

The Samsung SSD 990 Pro drives’ max IOPS ratings vary depending on queue depth, but peak at right around 1,200K – 1,550K at QD32. The drives’ endurance ratings also vary based on capacity, as you would expect, with the 1TB drive landing at the 600TBW mark and the bigger 2TB drive hitting 1200TBW, which is similar to the 980 Pros, but actually lower than the older 970 Pro series.

The Samsung SSD 990 Pro series features Samsung’s latest V-NAND flash memory. To be specific, the drives are equipped with, 1xx-layer (up to 144 layer) TLC 3-bit per cell V-NAND flash with 3D charge trap flash (CTF) cells. Samsung’s latest V-NAND offers lower latency for reads and writes, at similar or lower power than its previous-generation V-NAND.

The drives are also outfitted with a new controller. In addition to the native PCI Express 4.0 interface, the controller is manufactured on Samsung’s leading-edge 8nm process and reportedly offers a nearly 50% improvement in performance-per-watt. According to Samsung, the 980 Pro offers sequential Read / Write performance of 1,129MB / 877MB per watt, whereas the new 990 Pro can hit a sequential Read / Write of 1,380MB / 1,319MB per watt based on internal testing of the 1TB model.

The Samsung SSD 990 Pro’s controller supports all of the features you’d expect from a modern SSD, like TRIM, garbage collection, S.M.A.R.T., etc., in addition to various encryption technologies. Depending on the capacity, the first wave of drives also feature 1GB or 2GB of discrete LPDDR4 DRAM cache, with the 2TB drive packing the maximum config. The 4TB drive that’s coming later will have a 4GB LPDDR4 DRAM cache.

Like the last couple generations of Samsung Pro SSDs, the controller has a nickel coating that helps to dissipate heat and the underside of the drives has a thin plate hidden underneath the decal to aid in cooling. The drives also support Samsung’s Dynamic Thermal Guard, which helps manage power and thermals based on the drives’ workload to minimize any potential throttling.

Samsung SSD 990 Pro drives also feature TurboWrite technology, similar to Samsung EVO-branded drives. TurboWrite uses a portion of the drive’s V-NAND as an SLC write buffer, which results in improved write performance, as long as the buffer isn’t exhausted. As was the case with previous-gen drives, the TurboWrite buffer dynamically adjusts in size based on the workload.

TurboWrite will also allow the Samsung SSD 990 Pro drives to perform well in the vast majority of consumer-class workloads, because writes are fastest when the SLC buffer is being utilized. Once the buffer is exhausted, write performance can taper off, but on the 2TB drive we tested, the SLC cache is flushed fast enough to maintain strong write performance across the entire capacity of the drive.

Samsung warranties the SSD 990 Pro series drives for 5 years, which is in-line with previous-gen offerings, and the drives are also supported by Samsung’s Magician SSD management utility. Anecdotally, in all of the years we have been evaluating Samsung SSDs, we have yet to have one fail. Every one of the Samsung drives we have on hand, including much older SATA-based solutions, are still functional, for what it’s worth.

Samsung SSD 990 Pro PCIe Gen 4 SSD Benchmarks

Under each test condition, the SSDs showcased here were installed as secondary volumes in our testbed, with a separate drive used for the OS and benchmark installations. Our testbed’s motherboard was updated with the latest BIOS available at the time of publication and Windows 11 was fully updated. Windows firewall, automatic updates, and screen savers were all disabled before testing and Focus Assist was enabled to prevent any interruptions.

In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test. All of the drives here have also been updated to their latest firmware as of press time. Where applicable, we would also typically use any proprietary NVMe drivers available from a given manufacturer, but all of the drives featured here used the Microsoft driver included with Windows 11.

HotHardware’s Test System:

Motherboard: Gigabyte Aorus X570 Pro Wi-Fi (X570 Chipset)

Video Card: GeForce RTX 3080

Memory: 32GB G.SKILL DDR4-3200

Chipset Drivers: AMD v3.10.22.706

IOMeter Benchmarks

IOMeter is a well-respected industry standard benchmark. However, despite our results with IOMeter scaling as expected, it is debatable as to whether or not certain access patterns actually provide a valid example of real-world performance. The access patterns we tested may not reflect your particular workloads, for example. That said, we do think IOMeter is a reliable gauge for relative throughput, latency, and bandwidth with a given storage solution. In addition, there are certain highly-strenuous workloads you can place on a drive with IOMeter, that you can’t with most other storage benchmark tools.

In the following tables, we’re showing two sets of access patterns; a custom Workstation pattern, with an 8K transfer size, consisting of 80% reads (20% writes) and 80% random (20% sequential) access and a 4K access pattern with a 4K transfer size, comprised of 67% reads (33% writes) and 100% random access. Queue depths from 1 to 16 were tested.

At the lower queue depths, the Samsung SSD 990 Pro led the pack, but performance plateaued beyond QD4 and the other drives pulled ahead at the higher queue depths. Note that for consumer workloads, the lowest queue depths are most important, so the 990 Pro is in good shape here.

These numbers represent the average bandwidth for the drives we tested with both access patterns, across every queue depth. The Samsung SSD 990 Pro significantly outpaces the older 980 Pro and beats the Innogrit-based Adata drives, but the Phison-based drives come out on top.

Our latency results also show the Samsung SSD 990 Pro offering some of the lowest (best) latency at the lower queue depths. It’s only at the highest queue depth (QD16) that the 990 Pro’s latency trails the other drives.

SiSoft SANDRA 2021

Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. Here, we used the File System Test and provide the results from our comparison SSDs. Read and write performance metrics, along with the overall drive score, are detailed below.

The SANDRA file system benchmark has the top three drives offering similar read averages, with the Samsung 990 Pro landing right in between the Phison and Innogrit-based drives in terms its write average. Once again the 990 Pro clearly outruns Samsung’s previous flagship 980 Pro across the board.

ATTO Disk Benchmark

ATTO is another quick and dirty type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose.5KB through 64MB transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO’s workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.

Save for a dip with 64MB. 256MB block sixes in the write test, the Samsung SSD 990 Pro hangs with the fastest drives we tested according to ATTO.

IO performance according to ATTO had the Samsung SSD 990 Pro right in the mix with all of the other drives, though it does trail slightly in the read tests with the smallest transfer sizes.

AS SSD Compression Benchmark

Next up we ran the Compression Benchmark built-into AS SSD, an SSD specific benchmark being developed by Alex Intelligent Software. This test is interesting because it uses a mix of compressible and non-compressible data and outputs both Read and Write throughput of the drive. We only graphed a small fraction of the data (1% compressible, 50% compressible, and 100% compressible), but the trend is representative of the benchmark’s complete results.

The compressibility of the data being transferred across the drives has minimal impact on performance and the Samsung SSD 980 Pro performed well overall. In the read test, the 990 Pro is right in the mix with the other drives, but it leads slightly in the write test.

Which SSD is Better, Samsung or Crucial?

A Solid State Drive is a critical component in modern computing systems due to its significant importance. Unlike traditional hard disk drives (HDDs), SSDs utilize flash memory technology, resulting in lightning-fast data access speeds and improved system responsiveness. The absence of moving parts in an SSD enhances its durability and reliability, making it less susceptible to physical damage.

This speed and reliability translate into faster boot times, quicker application launches, and seamless multitasking, thereby significantly improving overall system performance. Furthermore, SSDs contribute to energy efficiency by consuming less power than HDDs, extending battery life in portable devices such as laptops.
