Anvil's Storage Utilities:
Anvil's Storage Utilities is another new benchmark designed with SSDs in mind. The standard storage benchmark measures a drive's performance by testing its transfer speeds, access times and IOPS.
Iometer:
Lastly, I ran a series of tests using Iometer. This tool can be configured to benchmark a number of things. In this case, I used it to measure the Ultimate SU900's read and write speeds and the number of operations per second. The tests were run using random bytes and a queue depth of 3.
The SU900's performance was very similar to what we saw in our other tests. The drive was able to read at 535.93 MB/s and write at 474.81 MB/s.
The SU900 also performed relatively well when doing random reads and writes. In our tests, the drive was able to read at 136.2 MB/s and write at 262.99 MB/s.
According to ADATA, the 256GB version of the SU900 is capable of 80,000 IOPS when reading and 90,000 IOPS when writing 4K blocks. In our tests, the drive reached 34,867 random read IOPS and 67,327 random write IOPS. As with most drives, the SU900 performed better at higher queue depths. With the queue depth set to 32, it reached 73,437 random read IOPS and 79,684 random write IOPS.
