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-256M6M'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-256M6M's performance was very similar to what we saw in our other tests. The drive was able to read at 497.66MB/s and write at 421.45 MB/s.
The PX-256M6M also performed relatively well when doing random reads and writes. In our tests, the drive was able to read at 126.31 MB/s and write at 242.43 MB/s.
According to Plextor, the PX-256M6M is capable of 94,000 IOPS when reading and 80,000 IOPS when writing 4K blocks. In our tests, the drive reached 32,334 random read IOPS and 62,062 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-256M6M reached 94,891 random read IOPS and 80,074 random write IOPS.
