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 970 EVO'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 970 EVO's performance was very similar to what we saw in our other tests. The drive was able to read at 3159.27 MB/s and write at 2392.66 MB/s.
The 970 EVO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 235.29.22 MB/s and write at a whopping 902.08 MB/s.
According to Samsung, the 2TB 970 EVO is capable of 500,000 IOPS when reading and 480,000 IOPS when writing 4K blocks. In our tests, the drive reached 60,235 random read IOPS and 230,934 random write IOPS. As with most drives, the 970 EVO performed better at higher queue depths. With four threads and the queue depth set to 32, it reached 365,971 random read IOPS and 442,705 random write IOPS.
