The Samsung SSD 850 EVO mSATA/M.2 Review
by Kristian Vättö on March 31, 2015 10:00 AM ESTATTO - Transfer Size vs Performance
I'm keeping our ATTO test around because it's a tool that can easily be run by anyone and it provides a quick look into performance scaling across multiple transfer sizes. I'm providing the results in a slightly different format because the line graphs didn't work well with multiple drives and creating the graphs was rather painful since the results had to be manually inserted cell be cell as ATTO doesn't provide a 'save as CSV' functionality.

AS-SSD Incompressible Sequential Performance
I'm also keeping AS-SSD around as it's freeware like ATTO and can be used by our readers to confirm that their drives operate properly. AS-SSD uses incompressible data for all of its transfers, so it's also a valuable tool when testing SandForce based drives that perform worse with incompressible data.

Eh... Nope. These won't work in the ThinkPads.blanarahul - Tuesday, March 31, 2015 - link
Hopefully, this drive will put an end to the mSATA/M.2 versions of the 840 non-EVO that companies are shipping in their laptops.Samus - Tuesday, March 31, 2015 - link
DoH! I just paid $20 more for the M550 (basically the MX100) 512GB M2 drive, which is double-sided and needs to be crammed into my laptop :\kgh00007 - Tuesday, March 31, 2015 - link
Hey, is there any chance you could fill one of these m.2 drives with data, power it off for a month then check the read speeds when you power it back on?I need some sort of evidence that this TLC V-nand does not have the same issues as the TLC in the 840 EVO.
Otherwise I'm not going to be able to buy one of these!
Cheers!

What the hell does not the charts compares with 840 ev msata ? Bad numbers Why not true sequential test ??And this site posting SUCKS, Why in the world I cannot use my facebook or so login, Did you know about disquss ? Get out the absurd captcha that fucking me 30 times or so trying to get a magical potion to know what the words saying,. THIS IS NOT ADVANCE IN TECH THIS IS TRASH

This is the third review with the new 2015 SSD Suite and I've only had limited time to test drives, hence the lack of 840 EVO in the graphs.goodyes - Wednesday, April 1, 2015 - link
Ya, but results that I have a 1TB 840 msata and write sequential at more than 500MBps around 520max MBps, and now I see than new 850 msata tops at ?? 480MBps ?? cannot be possible what my eyes look, AND WHY THE HELL NO ONE REVIEWER COMPARE With olders 840 msata, so I must think that all of you guys are a paid reviewers and you get money from samsung, if not, YOU MUST compare to older modelcgorange - Wednesday, April 1, 2015 - link
Other than providing samples, I can assure you that Samsung doesn't pay Anandtech to review its productsEkitrak - Wednesday, April 1, 2015 - link
The Final Words page has 2 entries of "Samsung 840 EVO mSATA" on the Amazon Price Comparison. I'm guessing this is an error and one of them is supposed to be the Sata III version?Kristian Vättö - Wednesday, April 1, 2015 - link
I'm not seeing this -- maybe you accidentally mixed up the 850 EVO mSATA and 840 EVO mSATA as they are both in the table (or maybe this was already fixed by another editor).
