MyDigitalSSD BulletProof 3 mSATA 256GB SSD Review – Availability, Capacity and Value

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.

Our ATTO results of 467MB/s read and 268MB/s write fell below the advertised specifications of 520MB/s read and 320MB/s write, however, did prove this SSD effective as a SATA 3 product.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. We are testing with ‘Random’ or highly incompressible data samples for the Bullet proof 3 as this drive does not use compression in storage and test results are very similar regardless of the data sample in use, compressible or incompressible.

Although such would not normally be the case, Crystal Disk Mark has improved our benchmark performance to 481MB/s read and 314MB/s write, the write performance falling in line with specifications for the most part.  This is the first opportunity that we had to see the all important low 4k random performance and 43MB/s is not up to par with what we would see in most SSDs these days.  This is typical of what we would normally see with the Phison S8 controller.

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.

Surprisingly, the access times shown are excellent although the  4k performance has taken its toll on the Point Score with only 383 points, a score we don’t typically rely on.

On the opposite end of the spectrum, we have some excellent transfer speeds and times as shown in the Copy Bench which can be credited to the Toshiba premium memory used.
