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-256M5M'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-256M5M's performance was very similar to what we saw in our other tests. The drive was able to read at 528.54 MB/s and write at 429.2 MB/s.
The PX-256M5M also performed relatively well when doing random reads and writes. In our tests, the drive was able to read at 145.47 MB/s and write at 220.49 MB/s.
According to Plextor, the PX-256M5M is capable of 79,000 IOPS when reading and 77,000 IOPS when writing 4K blocks. In our tests, the drive reached 37.242 random read IOPS and 56,445 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-256M5M reached 76,898 random read IOPS and 72,639 random write IOPS.
