BIOS 01.01.15 dated 12-18-2015 now applied, ATTO Disk Benchmark run again, most signficant change is somewhat faster write speeds. Full video of the test, and BIOS upgrade process, coming soon. Perhaps a Windows Update occurred that fixed something other than the still 6.0 Windows NVMe driver. Interesting, the performance has improved since December, don't really know why. Naturally, I have some further testing to do, to see if driver, power settings, BIOS settings, or other tweaks make a significant difference with the PM951. First look - Samsung SM951 M.2 SSD in a Supermicro SuperServer 5028D-TN4TĪTTO Disk Benchmark SM951 results on Supermicro SuperServer SYS-5028D-TN4T.Wow, funny he should ask this, because I know what the similar (but not identical) SM951 is capable of, having had some hands-on time with three of them, a couple of months back: I know PM951 is not as fast as 950 pro, but I wonder if its native use should be AHCI for faster performance What's also interesting is this dialogue going on with a TinkerTry visitor, who noticed his Dell (Core i5) arrived with RAID mode set, and was wondering if AHCI mode would result in faster numbers: It's apparently using whatever driver loads for NVMe that's built into Windows 10 Home (64 bit): Device Manager showing NVMe PM951 NVMe SAMSU driver version. This is just a baseline, to see how it compares to what others are seeing. Here's the results: ATTO Disk Benchmark PM951 512GB results on Dell XPS 15 Core i7 This is my first run, still using the default Windows 10 settings that were in this preload. With a need for virtualization performance and a bit of light gaming, the extra bit of umph of the Core i7 seemed worth the trade-off in battery life.Īfter firing it up, and letting Windows Update do its thing that included the time-consuming move from build 10286 to 10586.36, I couldn't resist giving ATTO Disk Benchmark a try.
