Samsung 840 EVO SSD Review – Samsung Caches In On Value and Performance

TEST BENCH AND PROTOCOL

Our analysis today will be conducted with our Asus Z77 Premium Test Bench. Clicking on any pictures or benchmarks will bring up a more easily viewable high resolution image.

In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 ‘safe mode’ to ensure the OS has little to no influence on the end result.

Test-Bench1

In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.

TSSDR-Test-Bench-Details

We would like to thank ASUS (P8Z77-V Premium), Intel (Core i7-3770K), Crucial (Ballistix), Corsair (H100) and Be Quiet (PSU/Fans) for supporting the build of our Z77 Premium Test Bench. In addition, we would also like to thank HighPoint for their contribution of the RocketStor 5322, RocketRAID 2711 and their External Mini-SAS to Esata cabling. Through this configuration we are able to benchmark all notebook and mSATA SSDs, whereby achieving identical performance as a direct system connection, yet we simply hot swap from the external storage dock.

BENCHMARK SOFTWARE

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities and PCMark Vantage. We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture. Much of the software is free and can be downloaded simply by clicking on the linked title.

EXPLORING SSD OPTIMIZATION

In all of our SSD testing, our benchmarks are conducted in a standard system with no SSD optimizations present.  The reason for this is that we want to be able to provide benchmarks that each and every reader can easily replicate, benchmarks that match manufacturers specifications. For this report, we are also going to include performance benchmarks of an optimized PC where the CPU states have been adjusted.  Specific explanation of this process is available in The SSD Optimization Guide and can be found on paragraph 19.  We strongly recommend that, should you wish to follow this or any of our other optimizations, read through the entire guide for a complete picture.

CRYSTAL DISK INFO VER 5.5.0

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not greyed out as with AAM.

super fast review – love ie

Great review Les. This drive is probably the most exciting development in the consumer SSD space to date. We can’t wait to get our hands on these down under in Australia.

Seems like a great SATA3 drive. However, I can’t help but feel like it’s a “bridge” drive. I mean, NGFF m.2 drives with direct PCIe connection are starting to appear, and they should have over 1GB/s read/write without any RAPID technology involved. This drive is for current systems that use a SATA port (99.999% of the market), but direct PCIe connection is the better way to go.

Wow….this could be a long response. You are absolutely right when you say that PCIe will be the future. It will take a few years, if not longer to completely implement, however, and manufacturers have already stated that it will have OEM, and not, retail availability initially. This makes great sense as there just isn’t the need for PCIe just yet. Samsung is striking at the present and want to get those that are yet to migrate, which is the majority of the population. The biggest obstacle with SSD transition has always been lack of knowledge and then fear of… Read more »

Agreed. However, for those of us regularly visiting this site, I think we are mostly looking for the latest and the greatest, which the EVO certainly represents, except for the SATA III bottleneck. Just like with 4G LTE data speeds being discussed in terms of “fast enough for most people”, and the same being the case as far as prowess of CPUs are concerned, we still want PCIe now instead of later. Mid-2013 MacBook Air owners are already there with Samsung again leading the way. Of course, there is also the issue of where would we plug in a PCIe… Read more »

There will be no 840 Evo Pro, but rather a future release of Samsung Magician with RAPID for the present Samsung Pro. Samsung is very happy with where they are at with the 840 Pro.

OK, so the 840 EVO replaces the 840 and then there’s the 840 Pro that remains, is that about right? Thanks so much for quick responses, Les. I need to choose a new SSD to buy either today or tomorrow, so I guess I can still buy the 840 Pro and get (most? all?) of the benefits of the EVO just with a software update?

Thanks again, you rule! (but you knew that… ;-P)

Will the Samsung Magician update for the 840 Pro ALSO help the 840 ?

You will have to clarify this a bit more.

Great and timely coverage. Thanks!

Am I the only one who believes that all SSDs (enterprise, prosumer and consumer) should have the supercaps installed?? The threat of data loss caused by a power interruption is rather nasty regardless of the users classification. I had hoped the EVOs would address this once and for all. With onboard memory caches getting larger and larger the potential for substantial data loss/corruption grows as well. It’s time for vendors to stop using supercaps as a marketing gimmick.
