Samsung 840 Pro 512GB SSD Review – Performance, Value, Battery Life and Untouchable IOPS

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. In the Samsung 840 Pro SSD, performance results are very similar whether we test with compressible or incompressible data and, for this reason, results are displayed utilizing incompressible data.  Of interest to note is how high we could increase performance by optimizing our systems power settings, this result shown on the right.

Prior to these results, I don’t recall ever seeing a high sequential write result of over 500MB/s while testing with incompressible data, incompressible data of course being that of music, movies and photos.  As much as the sequential, 512k, 4k read and 4K-QD32 are just about the best you can get on the result on the left, we would certainly liked to have seen the low 4k random write performance over 100MB/s without having to rely on optimization.  We believe that this performance may translate into amazing PCMark Vantage scoring.

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

Highlights of initial AS SSD testing are very quick disk access times and excellent 4k-64Thrd IOPS very close to specifications, which results in a very high AS SSD Total Score.  To complement this,  the AS SSD Copy Bench is also the highest result we have had to date, marking lightning fast transfer speeds.

ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)

You may not see this for long (and its definitely not common) but you get a freebee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

Some of the lesser- acknowledged qualities of this SSD are evident when we take a look at the response times (or disk access speeds) which are amazing.  IOPS hadn’t reached their top performance yet so we thought we might push the 840 Pro a bit to bring them up. The Total Score of just under 5000 is also front of the pack in all the SSDs we have tested to date.

For a typical form factor SSD (which can definitely be debated with the 840 Pro), reaching 100.000 IOPS at 4k-QD128 and 89,000 IOPS at 4k-QD64 does a great job of displaying the environments in which this SSD could function.

the CDM for Pro version looks very VERY promising. especially its 4k read write performance and access time, simply fantastic, great review!. only thing im hoping to see now is Data on drive test and it doesn`t look like SSDreview covers that portion of it as well as HD-Tune. I just wish to see from many aspect of the drive it`ll really help me make decision on purchasing SSDs.

looking forward to this comparing with SLC S301 and OCZ bigfoot, and intel 525.

sorry forgot to mention another thing, chances are I will not purchase 512gb drive at all, im not so sure about other people but cost is over double of 256gb drive, simply no point. imo with Trim in raid 0, double performance and same storage while at a cheaper value is the way to go.

any chance SSDreview will review 256gb of its drive?

You are on the case, the 256 drive should have been reviewed since it is the most common purchased due to the price/gb ratio!

Unfortunately, we review what we receive and, considering the very limited availability of samples to reviewers, we were ecstatic to receive this SSD and all that went with it. Stay tuned for the 250GB 840 review in the next day or so.

Awesome. Just as I expected.

My Samsung 830 have been reliable all this time with no faults or hiccups what so ever.

My laptops battery life increased a dramatic 30 minutes just by installing the 830. Now, I can expect even better results with the 840, of which I’m sure to buy.

How does it compare to an OCZ Vertex 4 with FW 1.5? Easy to say its at the top when you’re not comparing it with the latest and greatest from all of the vendors…

Fair game… This SSD was reviewed on release as was the OCZ. We have worked with the OCZ and it is a great drive, one of my favorites in fact. In a review and at the end of the day, all factors need to be examined and not a specific metric don’t you think? We can work on an updated comparison in the near future if you like.

Yea I think it’d be interesting to see it head 2 head with the Plextor M5s pro and the OCZ Vertex 4. Also, any news on the OCZ Vector yet? (You seemed to be the first to tip us off about the samsung 840) 🙂

imo this drive SHOULD be faster than both plextor m3p and m5p, vertex 4 doesnt even come close btw.. that low QD1 read.. OCZ will have to bring out it’s bigfoot drives in the next little while.

good thing about ocz vertex 4 is that its got 5k P/E write cycles i think. I am not so sure about samsung, probably 3k

Plextor M5P is reported to have a very good effect on battery life and with 19 nm I’d need a comparison before declaring this one the winner

Yeah!!! A MILLION TIMES THIS! Please review those top 3 drives head-to-head, please!

THIS drive has to be on your list of possibles for SSD needs. now, 3TB and lower cost…. goodbye HDD.
