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

TEST BENCH AND PROTOCOL

Article-View1Our analysis today will be conducted with our Asus Z77 Premium Test Bench.

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.

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.

Chassis

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.

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.

CRYSTAL DISK INFO VER 3.9.3

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.

As we can see, Samsung allows us only limited SMART information but we can confirm the firmware in use and that this is fully TRIM compliant.  Firmware will be another of the factors that differentiate between the 840 and 840 Pro, the Pro containing optimized firmware that enables the incredible IOPS performance up to 100, 000 IOPS.

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

ATTO highs of 559MB/s read and 524MB/s write surpass listed specifications of 540MB/s read and 520 MB/s write by a margin.  Also valuable to note in this test is how quickly these speeds are reached as transfer sizes increase.

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
