We proceed with the AS SSD benchmark, which contains five synthetic as well as three practical tests. The synthetic tests determine the sequential and the random read / write performance of an SSD. These tests are carried out without using the operating system's cache. The Seq-test measures how long it takes to read and write an 1GB file. Most importantly, this sequential benchmark uses incompressible data for all of its transfers.

The 4K benchmark tests the read and write performance for random 4K blocks. The 4K-64-THRD-test corresponds to the 4K procedure except that here the read and write operations are distributed on 64 threads.

The drive's performance in these tests was average, mainly due to the limitations of the SandForce controllers with incompressible data. The RevoDrive 3 120GB produced a good 398.01 MB/s read speed but a slower 148.324 MB/s write performance. The single-threaded 4K IOPS tests showed a high 20.88 MB/s for read and a faster write at 61.94 MB/s write, while the 64-thread 4K reads recorded a good 128.32 MB/s, and the write performance was significantly higher at 145.01MB/s:

In the following test, the RevoDrive 3 120GB SSD reads and writes files, which have been partially of fully compressed. It is obvious that the drive's performance peaks at high compression rates. The writing graph was not as smooth as the one we got in the reading test:
