TSSDR M.2 PCIE TEST BENCH
This new PCIe Test Bench build was the result of some great relationships and purchase; our appreciation goes to be quiet, Corsair, Crucial, Intel, EVGA and InWin for their support in our project. Our choice of components is very narrow, in that, we choose only what we believe to be among the best available and links are provided to each that will assist in hardware pricing and availability, should the reader be interested in purchase.

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal DiskMark, AS SSD, Anvil Storage Utilities, and PCMark Vantage. In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and, also, to provide validation to results already obtained.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
Performance highs of 2.1GB/s read and 1.7GB/s write of both Samsung XP941 M.2 PCIe SSDs displays perfect scaling with double the performance expected from a single 256GB capacity. The gradual and steady increase in performance, parallel to file size, also demonstrates a very strong setup.
Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible.
Crystal DiskMark didn’t fare as well as ATTO Disk BenchMark which was a bit odd as Samsung SSDs were created for testing in incompressible data samples. As a result of this test, we repeated it while testing with compressible data and there was no appreciable difference observed.
Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data. AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
AS SSD seems to display the strength of this RAID 0 configuration once again as it pushes performance to over 2GB/s. We found both the Total Score and IOPS a bit low considering. As well, some incredible speeds were reached when tests were done in AS SSD Copy Benchmark:
