Super Talent USB 3.0 Express RC8 50GB SSD Flash Drive Review – Crystal Disk Mark, AS SSD and Anvil Pro


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. Many new SSD owners who can’t wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.

We chose to use 0Fill or highly compressible data with Crystal Disk Mark as it would provide a bit of confirmation for the ATTO result although CDM scoring is typically a bit lower as can be seen here.  Of particular note, however, is the all important low 4k random write result of 48MB/s which is the highest we have seen in a USB drive.


Up until recently, ATTO 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 while using ‘SandForce Driven’ SSDs as they use compression in storage as discussed earlier.  Many enthusiasts like to AS SSD for their needs.

blankThe numbers look a bit different with AS SSD but, again, this is because we have moved to testing incompressible data in addition to the fact that AS SSD provides the final result as being the average of all tests whereas Crystal DiskMark looks for the highest result.  The 4k random write disk access score is key here as it is one of the best results we have seen from any flash drive.


The SSD Review has been fortunate to assist in beta testing of new storage benchmark software, called Anvil’s Storage Utilities, which is the best single benchmark we have seen to date. 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 utilize in our benchmark testing.

blankAnvil Pro provides us with a bit more information by displaying response times, MB read as well as a look at total IOPS.  The high sequential result of 244MB/s was as expected and, once again, a nice high score in the 4k random writes of 51MB/s is very encouraging.
