The Samsung 950 Pro PCIe SSD Review (256GB and 512GB)
by Billy Tallis on October 22, 2015 10:55 AM ESTATTO - Transfer Size vs Performance
ATTO provides a quick and easy test of performance over a range of block sizes, which makes it a good overview of performance. It illustrates quite clearly how performance plateaus as transfer size increases, with reads bumping up against the limits of SATA but writes being limited by the speed of the flash itself.
AS-SSD Incompressible Sequential Performance
Any drives that perform transparent compression will perform much worse on this test than the Iometer tests. The SandForce controllers that relied heavily on compression are much less popular (having been largely displaced by controllers from Silicon Motion, Marvell, and Phison), but this in still an important metric to keep in the suite. Many real-world sources of bulk data (such as encoded video) are already heavily compressed and cannot benefit from any attempts at further compression.
With a freshly-wiped drive and the short duration of the AS-SSD test, the drives perform much closer to their advertised speeds.

we need REAL-WORLD performance than synthetic benchmarksthis is like how it is with DDR speeds but they do absolutely like nothing even though bandwidth is like 10x in spread difference

" and in order to boot from an NVMe drive your motherborad's firmware needs NVMe support."^ Typo

Fixed! Thanks :)todlerix - Thursday, October 22, 2015 - link
How fast does the system boot with the 950 pros? I read the NVMe slows boot times down by a huge amount.Rajinder Gill - Thursday, October 22, 2015 - link
Considering most people only the system once per day, the wait should not be considered an issue. If one BOOTs the machine many times per day, S3 sleep is a quick way back to the desktop.Rajinder Gill - Thursday, October 22, 2015 - link

Even if I only boot my computer once per day, the time spent waiting for it to boot is annoying and I consider boot times important for that reason. When there is little other user-perceivable difference in SSD drives, a boot that happens 3 or 4 seconds faster is a significant factor.Makaveli - Thursday, October 22, 2015 - link
You know whats equally annoying people that sit and stare at boot screens lol.Go get a bagel, take a piss do something crying over 10 seconds isn't exactly productive.

This is called being enthusiastic about the wrong thing. If getting to the desktop matters that much to one's productivity, then using S3 resume would be the "logical" thing to do.Rajinder Gill - Thursday, October 22, 2015 - link
Shame on me for making a rational argument to irrational minds... ;)
