Samsung SM951-NVMe (256GB) PCIe SSD Review
by Kristian Vättö on June 25, 2015 9:40 AM ESTAnandTech Storage Bench - Heavy
While The Destroyer focuses on sustained and worst-case performance by hammering the drive with nearly 1TB worth of writes, the Heavy trace provides a more typical enthusiast and power user workload. By writing less to the drive, the Heavy trace doesn't drive the SSD into steady-state and thus the trace gives us a good idea of peak performance combined with some basic garbage collection routines. For full details of the test, please refer to the this article.
As the SM951 has been better optimized for typical client workloads than the SSD 750, it outperforms the Intel drive by a healthy margin. We don't really see much difference between the NVMe and AHCI versions, though, as the NVMe version has only marginally lower latency than it's AHCI sibling.

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).
