Testing (continued):

AS SSD Benchmark:

The final benchmark to consider is AS SSD, which is geared towards testing the read and write performance of just solid state drives. Results graphed below are all provided in units of MB/s, and higher is always better. We have sequential read and write tests, as well as read and write tests that utilize 4K random blocks. This test goes back to showing transfer rates for incompressible data, and Sandforce based SSDs don't make the best showing in this manner.

The sequential read results are shown below, and while 399MB/s is plenty fast, the MyDigitalSSD BP4 is zipping along at over 500MB/s.



When it comes to sequential writes, we see a familiar scene, with the Kingston mSATA drive finishing at just about 215MB/s.



When looking at 4KB random reads we see all of the solid state drives running rather "slowly", with scores in the 20-30MB/s neighborhood. Unfortunately, the Kingston mSATA drive doesn't quite make the 20's, and finishes last at just over 14MB/s.



Wrapping things up with AS SSD, we have 4KB random writes. The Kingston mSATA drive puts oup a score of 56MB/s, which still places it about 10MB/s slower than the MyDigitalSSD BP4 drive.
