Samsung SM951 (512GB) PCIe SSD Review
by Kristian Vättö on February 24, 2015 8:00 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.

The SM951 does much better at all IO sizes than the XP941 and especially read performance scales much better.
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.
Our sequential Iometer tests already showed that the SM951 is fast and AS-SSD provides further proof that the drive can easily reach ~1500MB/s.

Can't wait to see what Intel brings to the table considering the amount of focus they put on consistency.extide - Tuesday, February 24, 2015 - link
I'm not sure that we will see anything too interesting client side from them. They seemed to have moved all their focus to the enterprise side, which is of course where the bulk of the money is.FWIW, Intel already has a PCIe SSD that is arguably faster -- the Intel SSD DC P3700

It is faster, and certainly more reliable. Intel has the best enterprise SSDs on the market.FunBunny2 - Wednesday, February 25, 2015 - link
-- Intel has the best enterprise SSDs on the market.Among consumer facing companies, perhaps. The real enterprise SSD/flash players are largely unknown to AnandTech and its readers.

I'd love to see the results of a HDS FMD compared to the usual suspects.Kristian Vättö - Wednesday, February 25, 2015 - link
We've had this conversation before and I'll tell you this again: the majority of flash array vendors are using SSDs from Intel, SanDisk, Samsung and others. There are some that design and build their own drives/blades (e.g. Violin and Skyera), but the vast majority is using third party drives as the heart of their flash arrays.GTVic - Wednesday, February 25, 2015 - link
All drives now should support eDrive.Railgun - Tuesday, February 24, 2015 - link
At the rate I'm going, I'll end up with one of these before my XP941 ever gets powered up once, retail or otherwise.Laststop311 - Tuesday, February 24, 2015 - link
Disappointed in lack of 1TB size/ no 3d vnand/ no nvme. I planned on using 1 of these in 1TB size for a boot drive for a skylake-e build. The good news is I have a couple years for samsung to fix those issues.
