4/7/2023 0 Comments Amd raid monitor* Performance may vary based on SSD capacity, host hardware and software, operating system, and other system variables. Maximum 4K random read/write IOPS : up to 390K/380K All drives are 256GB in capacity, the detailed specifications are below for reference. Make no mistake, this motherboard is my favourite board of all time and has been since I first tested it last year I’d be building my next system around this component if I was undertaking a personal build right now.ĪDATA provided 4 SSDs for this project, 1xSATA SSD (an SX900 for a boot drive), and 3xM.2 NVMe drives for the RAID performance testing and instructional purposes. The star of the show was the AMD second generation Threadripper 2950X but the ASUS X399 ZENITH EXTREME motherboard allows the 2950X to shine. ADATA SX8200 Pro 256GB NVMe (3 drives in AMD NVMe RAID0).ASUS ROG X399 Zenith Extreme Motherboard.ASUS ROG X399 ZENITH EXTREME Test Rig Specification I’d like to give a massive shout out to AMD, ASUS, ADATA and Thermaltake for the products that we used. It’s a project like this that I really look forward to. The SU900 SATA SSD was tested in AHCI mode only and is used as a typical reference point for comparing the NVMe storage against the cheaper and slower SATA technology. We also benchmarked the same SX8200 Pro NVMe drive in NVMe mode and as a single drive in RAID mode to see if the controller mode made any difference to performance. We tested RAID 1 and RAID 0 (first with two NVMe drives, then retested with three in the array). ![]() ![]() The process may differ on other motherboard but the concept should remain the same. Another question we’ve had and also seen debated on forums was about the performance hit of RAID 1 where the drives are mirrored.Īll these questions will be answered with benchmarks and some step by step instructions on how we configured the ASUS X399 ZENITH EXTREME test System with an AMD Threadripper 2950X processor. We also had some reader questions about how well NVMe RAID scales given that these drives already operate at very high (relatively speaking) speeds in a standard configuration. Testing AMD NVMe RAID was something we had wanted to do for a while with the Threadripper platform due to the large number of PCIe lanes available from the CPU. This is a little more complicated for NVMe RAID due to the fact that each storage device needs PCIe lanes and these can be shared with graphics cards, networking devices, USB and other storage controllers. Motherboards typically have between 4 and 8 SATA ports for connecting hard drives or SSDs and configuring a RAID array is generally very simple so long as all the drives are the same capacity and speed. Sometimes system builders will use RAID for speed, sometimes for redundancy and sometimes for both. SATA hard drives and SSDs have been able to be configured in RAID via motherboard and discrete storage controllers for decades so it isn’t a new concept. RAID 0 – block level striping across all physical disks in the array without redundancy or parity.Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the required level of redundancy and performance.” “RAID (Redundant Array of Inexpensive Disks or Drives, or Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both…. RAID is best described at Wikipedia here but to cherry pick the relevant points: This is where the performance benefits of RAID might give power users or enthusiasts the storage speed edge they are looking for. RAMDISK capacities are limited and the cost per GB is prohibitive for large scale uses. The next step up after this is RAMDISK where volatile system memory is used but you still have to load the drive image into memory from a non-volatile location on boot. So we have ascertained that SATA SSDs are fast and can hit speeds up to about 550MB/s, with NVMe drives even faster again hitting speeds around the 3GB/s mark. NVMe drives transfer their data over PCIe lanes from either the CPU or the motherboard chipset and can run at much faster speeds than the alternative SATA technology. ![]() SATA SSDs are available in a 2.5″ form factor like the SU900 drive that you’ll meet in a minute or in an M.2 configuration. ![]() SATA SSDs (regardless of their connector) use the same interface as mechanical hard drives and top out at transfer rates of about 550MB/s. The legacy mSATA is still available but has been replaced by the M.2 socket and the mSATA socket is seldom found on modern day motherboards. All SSDs are significantly faster than hard drives with two main types available, SATA and M.2 NVMe. When you buy a modern system it will almost always come with an SSD.
