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 WD Black NVMe'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 WD Black NVMe's performance was very similar to what we saw in our other tests. The drive was able to read at 3067.18 MB/s and write at 2237.88 MB/s.

The WD Black NVMe also performed very well when doing random reads and writes. In our tests, the drive was able to read at 233.38 MB/s and write at an impressive 885.75 MB/s.

According to Western Digital, the 1TB WD Black NVMe is capable of 500,000 IOPS when reading and 400,000 IOPS when writing 4K blocks. In our tests, the drive reached 59,746 random read IOPS and 226,752 random write IOPS. As with most drives, the WD Black NVMe performed better at higher queue depths. With four threads and the queue depth set to 32, it reached 441,568 random read IOPS and 352,534 random write IOPS.
