Western Digital Black² Dual Drive Review

AS SSD
The AS SSD software determines the performance of Solid State Drives (SSD). The tool contains five synthetic and three practice tests. The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are performed without using the operating system caches. In Sequential tests the program measures the time it takes to read and write a 1GB file respectively. With most of the benchmark tests showing peak performance from an SSD, I’ve changed AS SSD a little to now give us a clearer picture as to how the drive will perform given variable levels of file compression.

Looking at the SSD performance we can see from the start that the JMicron controller is just as happy with incompressible data as it is with compressible. We also note that the write speeds on the SSD portion of the drive as a whole are notably lower than that of a standalone SSD with similar read performance figures.
