I've tested a number of other M.2 NVMe SSDs and decided to put a summary up here:
http://apollo.backplane.com/DFlyMisc/nvme_randread.txt I have now been able to add the Intel 600P, Toshiba OCZ, and Samsung 960 EVO. I'll be able to test the Crucial later when it gets delivered. I previously tested the Samsung 951 and the Intel 750. I don't include the 750 in this URL because its a larger, expensive PCIe card. I'm focusing on the M.2 tests. All SSDs were tested in a Xeon system with PCI-3.0 sockets, placed in a PCIe card carrier for M.2. My conclusion, so far, is that the Samsung SSDs offer the best performance, value, and safety. The Intel 600P is a piece of junk (never buy one), and while the Toshiba did very well in performance tests it also got rather hot, topping out at 81C, and didn't flag the over-heat or auto-throttle insofar as I can tell. The Intel actually did auto-throttle. Neither Samsung over-temp'd. The 960 EVO stayed very cool, in fact. I'll add the crucial when I get it and put it through its paces. -Matt
