S: Samsung 970 EVO Plus – SQL Server user database data filesįor larger databases, I plan on having a MAIN file group with two data files that will have one data file on the R: drive and one data file on the S: drive.R: Samsung 970 EVO Plus – SQL Server user database data files.L: Samsung 860EVO – User database log files.C: Samsung 980 PRO – OS, SQL Server binaries, system databases (except tempdb).I’ll be running at least two named instances of SQL Server, with my various database files deliberately spread out across these drives. The moral of the story is that you should consult your motherboard manual to avoid making mistakes like this! What Are You Doing With All Those Drives? If you try to put something in every PCIe slot, every M.2 slot, and every SATA port, you will have probably have some issues. Many motherboards and chipsets have conflicts like this as you add more devices to your system. That is what I did, which was quick and easy. The other solution would be to connect my two SATA drives to different SATA ports that did not share bandwidth with the 3rd PCIe slot. The problem with that is that it puts the Intel 900P too close to the Radeon 5700XT video card, which would reduce the effectiveness of the cooling fans on the video card. One would be to move the Intel 900P from the third PCIe slot to the second PCIe slot. Once I realized this, I had two ways to fix the issue. This smaller capacity SKU has lower write performance than the 1TB or upcoming 2TB models. Keep in mind that this is only the 500GB size of the Samsung 980 PRO. The Samsung 980 PRO is my boot drive, and it is in the M.2 slot closest to the CPU. That high queue depth makes NAND storage look better. Here they are from the fastest to the slowest. I did some quick and dirty I/O testing of these six drives with CrystalDiskMark 7.0.0. Finally, the Intel Optane SSD is using the Intel NVMe driver version 5.1 Some Quick Comparative CrystalDiskMark Results in 2020 Samsung has not released an NVMe driver for the Samsung 980 PRO, and I don’t think they are planning on it. The Samsung 980 PRO is using the Microsoft NVMe driver, while the Samsung 970 EVO Plus drives are using the Samsung NVMe driver version 3.3. 280GB Intel Optane 900P PCIe 3.0 NVMe SSD.(2) 1TB Samsung 970 EVO Plus M.2 PCIe 3.0 NVMe SSD.500GB Samsung 980 PRO M.2 PCIe 4.0 NVMe SSD.There are three M.2 PCIe NVMe SSDs, one AIC PCIe NVMe SSD, one 2.5″ SATA SSD, and one 3.5″ SATA HDD. PCIe 4.0 has twice the bandwidth per lane compared to PCIe 3.0. The latest generation video cards from both AMD and NVIDIA support PCIe 4.0. In my case, I have an AMD Radeon 5700XT video card that is PCIe 4.0. You can minimize any possible impact from this by using a PCIe 4.0 video card instead of a PCIe 3.0 video card. This might sound bad, but it is actually not a problem for most scenarios. That means eight PCIe lanes instead of sixteen lanes. If you use the 2nd or 3rd M.2 slot (even for a PCIe 3.0 device), it causes the primary PCIe slot to go from PCIe 4.0 x16 down to x8. Nonetheless, an excellent product from WD.The B550 AORUS MASTER has three M.2 PCIe 4.0 slots that are all connected to the CPU. ![]() Then again, if I were concerned about warranty/TBW or sequential throughput, the FireCuda 530 might get the nod. Random performance is what makes operating systems seem quick, and that is where the SN850X shines. If I was choosing a drive to anchor a new test bed, it would be the WD Black SN850X. SSD performance can vary by capacity due to more or fewer chips to shotgun reads/writes across and the amount of NAND available for secondary caching. The performance numbers shown apply only to the drive of the capacity tested. Over time, as a drive fills up, performance will decrease due to less NAND for caching, and other factors. Copy tests utilize an ImDisk RAM disk employing 58GB of the 64GB total memory.Įach test is performed on a newly formatted and TRIM’d drive so the results are optimal. Internal drive tests currently utilize Windows 11, 64-bit running on an MSI MEG X570/AMD Ryzen 3700X combo with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB PCIe x2 graphics card, and an Asmedia ASM3242 USB 3.2×2 card. What it didn’t show in CrystalDiskMark 8 in terms of sequential throughput, it demonstrated in the real world. As you can see, the SN850X lacks nothing in performance. ![]()
