The Samsung 950 Pro PCIe SSD Review (256GB and 512GB)
by Billy Tallis on October 22, 2015 10:55 AM ESTAnandTech Storage Bench - Light
Out Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so application launch times and file load times are what dominate this test. Details of the Light test can be found here.
The Light test starts to show a distinct advantage for NVMe, and the Samsung UBX controller is performing much better than Intel's SSD 750.
The three Samsung NVMe drives have the lowest average service time and the SATA drives are all looking quite slow by comparison.
The PCIe drives are all very good about keeping latency outliers to a minimum, but none have yet managed to complete the entire test without any request taking more than 10ms.
Despite stellar performance, the 950 Pro's power efficiency is poor. If our system could make use of some power management capabilities this situation could be very different, but for many consumers this is just the way things are for PCIe drives. The lack of power management support may be slightly helping some of the latency scores, as transitioning between power states usually requires a short interruption in service.

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

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... ;)
