Samsung PM841 512GB mSATA SSD Review – Performance and Capacity in a Client SSD

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 Bench

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.

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.

SAMSUNG SSD MAGICIAN VER 4.0

Samsung Magician software is available for consumer SSDs, however does not fully function with the PM 841 mSATA SSD. It does, however, allow for drive performance specs to be confirmed as seen here:

Thanks for the review, was looking to find a good high capacity SSD for my Ultrabook. Looks like I can swoop up the Samsung instead of the Atlas which I was hesitant about.

They are sold out presently and expect to be until the 28th. We have several e-mails already regarding lack of stock.

Are there any updates on ETA on the PM841 512GB? I’ve been looking everywhere but no one has them in stock!

They apparently sell out faster than they can et them in. I might contact the seller listed on Amazon and see if you can reserve one.

I’m wondering if this 512GB will be used in the new Samsung Series 900X3E (1080p screen). In USA, NP900X3E-A02US=128GB, NP900X3E-A03US=256GB and there is no trace of 512GB. While in UK, NP900X3E-A01UK=256GB, NP900X3E-A03UK=512GB and there is no trace of 128GB. Totally confusing. As of end of April, only NP900X3E-A02US is available at Amazon. I think that I will buy NP900X3E-A02US, then buy and replace by a 480GB Muskin. I hope that the Series 900X3E uses a mSSD and Muskin can fit into it. Samsung (like Apple) really overprices the storage as $(NP900X3E-A03US) – $(NP900X3E-A02US) ~ $500 >> expected $1 * 128GB… Read more »

If you were hoping fot the reviewed drive, isn’t that cheaper than the Mushkin? They sold out within a day but should be restocked and available by end month so stay tuned. Nice systems though but I can’t see Samsung making a 512GB standard as it would cost too much for purchase. We should be happy that they are using their own mSATA SSDs finally…or are they?

Thanks for the review. I don’t see any other large capacity SSDs out there so I’ll be keeping an eye out for when they come back in stock. I presume these would be compatible with most systems? I have a Lenovo Ideapad Yoga 13…

Any chance to get firmware upgrades here? mine isn’t recognized by the Magician software from Samsung.
(btw. the SSD came with my 900X4D)

Any chance to get firmware upgrades here? mine isn’t recognized by the Magician software from Samsung. Funny hitch though having bought it in a Samsung system and still not being able to use it with the Magician. Did Samsung Magician come pre-installed on the machine?

No it wasn’t unfortunately… I installed it myself to give it a try. I just read somewhere that the Magician supports consumer SSDs only and it seems like the PM841 isn’t one of those.
