Anvil's Storage Utilities:
Anvil's Storage Utilities is another 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 980'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 Gold P31's performance here was similar to what we saw in our other tests. The drive was able to read at 3385.87 MB/s and write at 3341.16 MB/s.
The 2TB Gold P31 didn't perform as well as the 1TB version when doing random reads and writes. Nevertheless, the drive was able to read at 291.13 MB/s and write at 556.51 MB/s.
According to SK hynix, the 2TB Gold P31 is capable of 570,000 IOPS when reading and 600,000 IOPS when writing 4K blocks. In our tests, the drive reached 74,528 random read IOPS and 142,440 random write IOPS. As with most drives, the Gold P31 performed better at higher queue depths. With sixteen threads and the queue depth set to 32, it reached 517.405 random read IOPS and 665,034 random write IOPS.
