MyDigitalSSD BP4 Slim 7 Series SSD Review (240GB)

TEST BENCH AND PROTOCOL

Our analysis today will be conducted with our Asus Z77 Premium Test Bench.

In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 safe mode to ensure the OS has little to no influence on the end result.

In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.

We would like to thank ASUS (P8Z77-V Premium), Intel (Core i7-3770K), Crucial (Ballistix), Corsair (H100) and Be Quiet (PSU/Fans) for supporting the build of our Z77 Premium Test Bench.

BENCHMARK SOFTWARE

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities and PCMark Vantage.  We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture.  Much of the software is free and can be downloaded simply by clicking on the linked title.

CRYSTAL DISK INFO VER 5.0.5

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not greyed out as with AAM. Identification of SMART data leaves something to be desired with the BP4.

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.

Specific to this ATTO benchmark, take a look at the 4K read performance of 384MB/s.  We thought this was the fastest we had seen to date so decided to pull up the reviews of our two top drives, the Samsung 840 Pro and OCZ Vector.  As much as the combined read and write performance for both is better at the 4k level, it is worth noting that the performance of the BP4 is significantly higher than both in 4k read performance.

We wondered whether this could simply be a fluke and pulled up the result of the 120GB BP4 we had just tested which, coincidentally topped at 391MB/s.  Because this Toshiba 19nm memory is so new, we can’t lay complete faith in this performance being responsible for this boost, but will be keeping a close eye on this in future reviews that utilize this memory.

    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

    • Even better than numbers, your system will realize a significantly quicker start time and visible performance upgrade…and it is a great price!
