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.
WD Black² SSD
WD Black² HDD
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 Black²'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 Black²'s performance was very similar to what we saw in our other tests. Where the SSD portion of the drive was able to read at 473.44 MB/s and write at 138.36 MB/s, the HDD portion was able to read at 103.17 MB/s and write at 93.49 MB/s.
The random read and write performance of the SSD portion of the Black² was hit and miss. While the drive was able to read at a respectable 104.11 MB/s, its random write speed topped out at only 138.55 MB/s. As you'd expect, the HDD portion was considerably slower when doing random reads and writes. In our tests, its random write speed topped out at a mere 1.17 MB/s.
Western Digital doesn't really say what the Black² is capable of in regards to IOPS. In our tests, the SSD portion of the drive reached 26,652 random read IOPS and 35,468 random write IOPS. Once again, the HDD portion lagged well behind, reaching 190 random read IOPS and 299 random write IOPS.
