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.

Our first benchmark, ATTO, shows that the SBX is capable of almost 1.8GB/s read speeds and write speeds vary from capacity to capacity. The 128GB model writes at up to 465MB/s, the 256GB model writes at up to 896MB/s, and the 512GB model writes at just over 1GB/s.
CRYSTAL DISK BENCHMARK VER. 6.0.0 X64
Crystal Disk Benchmark is used to measure read and write performance through a sampling of 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.

Testing in Crystal Disk Mark shows us very similar results. All are capable of sequential read speeds of about 1.5-1.6GB/s. Write speeds are 486MB/s, 916MB/s, and 1040MB/s for each, respectively. 4K QD1 performance is very good with reads averaging 45MB/s and writes averaging 170MB/s.
The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

In AS SSD, the 128GB MyDigitalSSD SBX achieved an overall score of 1508 pints, the 256GB model achieved 2359 points, and the 512GB model achieved 2580 points. All show read speeds at up to almost 1.5GB/s and write speeds are similar to what we have seen previously.
Additionally, we can see that during the AS SSD Copy test that all capacities averaged pretty similar times despite their differences in pure write performance.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) is the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

Anvil Storage Utilities once again confirms all the performance numbers we have been seeing and overall, the MyDigitalSSD SBX achieved scores of 6134, 7582, and 7872 points, increasing as capacity increases.
