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 Plus'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 Plus's performance was very similar to what we saw in our other tests. The drive was able to read at 3148.19 MB/s and write at 2268.99 MB/s.
The 970 EVO Plus also performed very well when doing random reads and writes. In our tests, the drive was able to read at 227.59 MB/s and write at a blazing 787.72 MB/s.
According to Samsung, the 250GB 970 EVO Plus is capable of 250,000 IOPS when reading and 550,000 IOPS when writing 4K blocks. In our tests, the drive reached 58,267 random read IOPS and 201,657 random write IOPS. As with most drives, the 970 EVO Plus performed better at higher queue depths. With four threads and the queue depth set to 32, it reached 147,364 random read IOPS and 362,445 random write IOPS.
