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

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Our Crystal DiskMark results seem to fall in line with what we received from the Samsung Magician Performance Benchmark. The most noticeable result in this benchmark is the low 4K random write performance of 685MB/s which has never been seen prior.

AS much as this low 4K result may once again be a false negative, one has to wonder as Samsung clearly stated that RAPID Technology was targeting highly incompressible (random) low QD small write files which are exactly what we have here.

This AS SSD Copy Benchmark is very interesting as its result shows a definite performance increase to any result we have seen prior.  This benchmark is also just about as ‘true to life’ as you can get for tersting as it comprises of simply moving three files from one place to another on the SSD.  The result depicts the high transfer speed reached and the time it took to complete the transfer.

Once again, the transfer speeds fall right in line with what we have been seeing, as well as the low 4K IOPS.  Discarding any high QD 4K results in testing seems to be the logical thoughts which, again, coincides with Samsung’s description of it’s target disk transfer characteristics.

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.

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.
