Solidata K8 1920E 2TB SSD Review – Highest Capacity 2.5″ Form Factor SSD To Date

ATTO DISK BENCHMARK VER. 2.46

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.

Highs of 239MB/s read and 248MB/s write performance exceed listed specifications of 230MB/s read and 200MB/s write, remembering of course that this is a 3Gbps SSD.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

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. We have provided the results of testing in highly compressible data on the left and that of highly incompressible data on the right.

AS SSD BENCHMARK VER 1.6

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.

Once again, if you look at the Total Score alone, you may get a bit hesitant but AS SSD is very reflective of this SSD in transfer performance of incompressible data and shows that the IOPS reached higher than listed specs.
