SAMSUNG M.2 RAID0 X 3 BENCHMARKS
Let’s start with a three m.2 NVMe SSD RAID configuration as this was the goal of our report, to create a triple NVMe SSD RAID that was bootable. In testing in both RST RAID through the UEFI and through the Win 10 OS, we discovered a few interesting throughput differences. In the benchmarks below, each is clearly identified as being ‘RST RAID’ or ‘OS RAID’.
ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.
Looking at the way both RAID volumes deal with compressible data in ATTO, we noticed a rather significant throughput read difference in higher file sizes, 2.9GB/s for the UEFI RAID and 2.6GB/s for the Win 10 RAID.
Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.
When we take a look at Crystak Disk Mark results, things change just a bit. The Windows 10 OS RAID seems to have better performance in this test, especially in looking at low 4k random write data throughput.
AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected.
