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 Vertex 450'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 Vertex 450's performance was very similar to what we saw in our other tests. The drive was able to read at 525.92 MB/s and write at 490.07 MB/s.
The Vertex 450 also performed pretty well when doing random reads and writes. In our tests, the drive was able to read at 97.02 MB/s and write at 269.12 MB/s.
According to OCZ, the 256GB version of the Vertex 450 is capable of 80,000 IOPS when reading and 90,000 IOPS when writing 4K blocks. In our tests, the drive reached 24,837 random read IOPS and 68,894 random write IOPS. The only way I came close to OCZ's numbers was to increase the queue depth. With the queue depth set to 32, the Vertex 450 reached 85,191 random read IOPS and 84,289 random write IOPS.
