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.
Looking at the Plextor M6e in RAID0, we can se that it reaches 1.3GB/s read performance. As well, the high sequential write performance of the M6e 512GB SSD was well above listed specs.
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. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
When comparing Crystal DiskMark performance to that of ATTO typically, we would see a very noticeable drop because ATTO uses highly compressible data samples, whereas CDM uses highly incompressible samples.
It is good to see that, for the most part, the caliber of the Plextor M6e shines through, regardless of the data samples we throw at it.
