![]() Keep in mind that the two Samsung 850 PRO SSDs are using hardware RAID1, which seems to help their sequential read performance, and that the two NVMe devices are both using the native Microsoft NVMe drivers, which may be hurting their performance somewhat.įigure 1: 512GB Samsung 950 Pro M. Table 1: Sequential and Random Results (Queue Depth 32, 1 Thread) As you can see below, both the Samsung 950 PRO and the Intel 750 PCIe NVMe cards have tremendous sequential and random I/O performance! Device The two NVMe devices are both using the native Microsoft NVMe drivers from Windows 10. I did some quick and dirty I/O testing today with CrystalDiskMark 5.02. Vengeance RGB PRO DDR4 3200 C16 2x8GB Corsair 55 Bench 85, 346,786 samples. Vengeance LPX DDR4 3200 C16 2x8GB Corsair 48 Bench 85, 653,654 samples. This system has Windows 10 Professional installed, so it has native NVMe drivers available from Microsoft. 970 Evo Plus NVMe PCIe M.2 1TB Samsung 70 Bench 310, 455,997 samples. Sequential performance is good, but not that good either. ![]() The Intel Z170 Express chipset supports 26 PCIe 3.0 lanes, so you need to think about what devices you are trying to use. 4K Random Write Speed (Q32T1): 5 MB/s Comparing Kingston A400’s claimed 500MB/s read and 320MB/s write speeds for the 240 GB model with the results from CrystalDiskMark, we see that there’s a huge gap in write performance. Since I have an NVidia GeForce GTX 960 video card in one of the PCI 3.0 x16 slots, both that slot and the PCI 3.0 x16 slot that the Intel 750 is using will go down to x8 (which means 8 lanes instead of 16 lanes). (1) 6TB Western Digital SATA III hard drive in a SATA III port.(1) 400GB Intel 750 PCIe NVMe card in a PCIe 3.0 x16 slot.(1) 512GB Samsung 950 PRO M.2 PCIe 3.0 NVMe card in an Ultra M.2 PCIe 3.0 x4 slot.(2) 512GB Samsung 850 PRO SATA III SSDs in RAID 1 (using the chipset RAID controller).As of now, here is the available storage in this system: The latest addition to the storage family is a brand new 512GB Samsung 950 PRO M.2 PCIe NVMe card that just arrived from Amazon yesterday afternoon. By design, this system has several different types of storage devices, so I can take advantage of the extra PCIe bandwidth in the latest Intel Z170 Express chipset, and do some comparative testing. I have some details about this system as described in Building a Z170 Desktop System with a Core i7-6700K Skylake Processor. Check them out here.)Ī few weeks ago, I built a new Intel Skylake desktop system that I am going to start using as my primary workstation in the near future. RandomWrite 4KB (QD=32) : 7.(New: we’ve published a range of SQL Server interview candidate screening assessments with our partner Kandio, so you can avoid hiring an ‘expert’ who ends up causing problems. Wednesday after restoring from having a ramdisk: I may request the Beta firmware from RamGuy, but I already did 2 complete installs, and I don't look forward to that again. A five-year warranty is standard, but we’re more impressed with FireCuda 530 being bundled with three-year cover for Rescue. Putting it another way, that’s well over 1,000 complete drive writes before any fragility is observed. One thing I noticed is that EVGA precision needs to be disabled or else the score can be a fair amount lower as indicated on 11/24. The 2TB sample carries impressive specifications in every area, and the 2.55PB endurance rating is class-leading. Below is a series of benchmarks for my P128 with a Nvidia 790i motherboard, the AHCI is not an option.
