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 870 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 870 EVO's performance was very similar to what we saw in our other tests. The drive was able to read at 538.26 MB/s and write at 512.27 MB/s.
The 870 EVO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 184.73 MB/s and write at an impressive 361.47 MB/s.
According to Samsung, the 870 EVO is capable of 98,000 IOPS when reading and 88,000 IOPS when writing 4K blocks. In our tests, the drive reached 47,291 random read IOPS and 92,535 random write IOPS. Increasing the queue depth had little impact on the 870 EVO's random write performance. However, with four threads and the queue depth set to 32, the drive was able to reach 99,348 random read IOPS.
