MyDigitalSSD BP4 Slim 7 Series SSD Review (240GB)


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. In the MyDigitalSSD BP4, we have provided the result with random data samples as both results were extremely similar.

Typically, we might see significantly lower results when comparing ATTO to Crystal DiskMark but the high sequential read result of 516MB/s is very good, once again leaving us to consider whether the Toshiba memory could play a part in this.


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.

You may not see this for long (and its definitely not common) but you get a free-bee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  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.

Anvil Storage Utilities confirm what we have seen from other benchmarks including the high IOPS of 62, 876 which falls a bit lower than that listed in specifications.

    Very nice assessment!
    So, would you recommend to replace the current 5400rpm HD in my laptop by the MyDigitalSSD BP4 Slim 7 Series SSD and expect an improvement in overall laptop performance? Currently the WEI (windows experience index) is 5.9 because of the HDD data transfer rate, which is determined by the lowest subscore. The next lowest subscore is 6.5 determined by the graphics card. Thanks for your opinion
