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.

And why would these people boot it every day?Rajinder Gill - Friday, October 23, 2015 - link
If speed matters that much, use S3 resume, it is the fastest way back to the desktop. :)Samus - Friday, October 23, 2015 - link
I reboot my PC 3 times a year. I could give two shits in a cup about boot times.5th element - Monday, October 26, 2015 - link
Couldn't. It's couldn't give two shits not could.Beaver M. - Thursday, October 22, 2015 - link
With the beta NVMe driver it takes about 300 ms longer.geniekid - Thursday, October 22, 2015 - link
http://techreport.com/review/29221/samsung-950-pro...Based on that link I would say issues with NVMe boot times are largely firmware issues that are being rectified.

If they updated their baseline every time new tech came out then they would be so busy retesting to have comparable results, that we would never see a new review ever again.AnnonymousCoward - Thursday, October 22, 2015 - link
Thanks geniekid! That review is far more valuable than what we have here on AT. AT said "loading a new level in a video game would be more likely to show noticeable difference from better performance here". More likely, huh. Then you go look at the actual data at techreport and find there's nearly zero difference. When will AT learn to measure an SSD in an actually useful way?StrangerGuy - Thursday, October 22, 2015 - link
Game load times are actually the least sensitive to SSD speeds. Even a 15 year old game like Red Alert 2 with a next to zero RAM footprint certainly doesn't load instantly on a Crucial M550, much less current titles.
