 En annen oppgradering vs SM951 :

 

 

As for the 950 Pro’s controller, Samsung is using their UBX controller here. This is the same controller that is featured in the existing SM951 OEM drives, making the big difference versus SM951 the use of V-NAND versus planar. Like the SM951, this means Samsung is using 512MB of memory to back the SSD controller, upgrading from LPDDR3 to LPDDR4.

Lurer på om Samsung har klart å få orden på varmeploblemene som M2 SSD'er sliter med :hmm:

Min er ikkje varm, så det har bok noe med luft i kabinettet og om varmt skjermkort er rett over den. Jeg gar vannkjøling og ssden blir ca 40 grader med 5GB test i asssd. Ikkje vann på ssden nei :p Endret av Nizzen

In our open air test bench we quickly found out that we were experiencing performance throttling due to overheating.

 

Once we noticed that the drive was throttling we stopped our testing and did some investigating on the SM951. With the drive in a used very dirty state we logged the drives temperature during a 15 minute sequential write and found that in just just 130 seconds that our drive went from an idle temperature of 35C to the throttle point of 82C! Our performance went from being ~1500MB/s all they way down to 70MB/s during the throttle as a way to cool the drive down by what we are guessing is a short term cut in power and operations on the controller.

 

 

 

Because the SM951 is an M.2 drive, it doesn't have a chassis or heatsink to help with the heat dissipation, which combined with the fact that the SM951 is more power hungry than most SATA 6Gbps drives results in throttling issues.
