The next benchmark is the Anvil Pro, an ‘all inclusive’ storage utility. The software is tests transfer speeds as well as IOPS The IOPS tests can be configurable with preset testing scenarios for read (Seq 4MB, 4K, 4K QD4, 4K QD16, 32K and 128K), write (Seq 4MB, 4K, 4K QD4, 4K QD16) and mixed IO.

We used the software with the Crucial MX300 SSD and tested the drive with 0-fill compression (RAW), 8% compression, 25% compression, 45% compression, 67% compression and finally 100 % (incompressible data).

Generally, the results we got from the Anvil Pro benchmark unveiled a consistent performance for the Toshiba OCZ RD400 512GB GB across different compressions.

The RD400 ranked second in the sequential read test:

Toshiba's drive was a bit slower than the Samsung 950 Pro in the 4K read tests:

The RD400 gave 1040,65 MB/s in the sequential write benchmark, following the leading 950 Pro. However, Toshiba's drive took the first place in the 4K write (QD4, QD16) tests:
