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 PX-256M5P'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 PX-256M5P's performance was very similar to what we saw in our other tests. The drive was able to read at 529.49 MB/s and write at 444.24 MB/s.

The PX-256M5P also performed pretty well when doing random reads and writes. In our tests, the drive was able to write at 261.45 MB/s and read at a blazing 160.05 MB/s.

According to Plextor, the PX-256M5P is capable of 94,000 IOPS when reading and 86,000 IOPS when writing 4K blocks. In our tests, the drive reached 40,972 random read IOPS and 66,930 random write IOPS. The only way I came close to Plextor's numbers was to increase the queue depth. With the queue depth set to 32, the PX-235M5P reached 94,238 random read IOPS and 81,665 random write IOPS.
