Samsung SM951-NVMe (256GB) PCIe SSD Review
by Kristian Vättö on June 25, 2015 9:40 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.

They aren't all storage transfer commands go through the PCH. Your PCIe SSDs do not connect to the CPU directly in most cases. Some enterprise grade drives do, but most consumer do not.Kristian Vättö - Friday, June 26, 2015 - link
PCIe is PCIe regardless of whether the controller is inside the CPU or PCH. PCH merely acts as a hub for different interfaces, but ultimately it connects to the CPU as well since that is where all the processing is done.CajunArson - Thursday, June 25, 2015 - link
Yeah so are we missing some sound and FURY [hint hint] about this SSD on a stick?Kristian Vättö - Thursday, June 25, 2015 - link
Fury X is coming, Ryan just needed one more day because the flu has been undermining his ability to work.DigitalFreak - Thursday, June 25, 2015 - link
(hint hint) The 980ti is faster than the Fury X all around.CajunArson - Thursday, June 25, 2015 - link
I'm not disagreeing with that statement.I just want the review.

+1A DX12 showdown between FuryX and 980ti would be highly welcome as well.

The Fury X wins in some of the 4k tests. The 980Ti seems faster overall, but it's not "all around".mr_tawan - Friday, June 26, 2015 - link
From what I've read, it looks like the Fury has advantages when it comes to memory-intensive use case.SofS - Thursday, June 25, 2015 - link
About the driver issue, how do different operating systems fare? Like 32/64 bits, XP/7/8/10 and Linux old/new (for instance CentOS/Fedora).
