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

REPORT ANALYSIS AND FINAL THOUGHTS

The Samsung PM841 512GB SSD reigns as the largest capacity mSATA SSD available (or not available) to date. Where Crucial has relied on over provisioning of their recently released M500 480GB version, Samsung is comfortable with the higher capacity and the benefit of capacity goes to the end user.

The downfall of the Samsung PM841 is that it is not available as a consumer retail item, unlike the remainder of the 840 family. This is disappointing because healthy competition would be great with this form factor and capacity. Looking at Amazon at the time of this report, the Samsung PM841 mSATA SSD is now available in 128, 256 and 512GB capacities for $129, $249 and $449 which is under $1/GB for the two higher capacities.

Performance for the PM841 stands on its own, literally speaking, as we haven’t another similar capacity mSATA SSD yet that doesn’t use compression in it’s storage like the Mushkin 480GB Atlas mSATA SSD. Performance (and size) between the two is incomparable as they both have superior qualities, the PM841 definitely standing out with its high IOPS of over 90,000 and the fact that it is a thinner form factor with single PCB. The ‘Achilles Heal’ of the PM841 has to be the fact that a typical Samsung warranty would be impossible to find, as with the remainder of the 840 Pro family.

FINAL THOUGHTS

Samsung needs to market the PM841 mSATA SSD as a member of the 840 Pro family. If this were the case, we would have no hestitation whatsoever in awarding it with the Editor’s Choice because this would address availability concerns in the future. Utilizing their 21nm memory in a 128GB module capacity is a first though and moves us one step forward in SSD technology. For this, we are awarding the PM841 our Innovation Award.

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.
