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 980'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 980's performance here was similar to what we saw in our other tests. The drive was able to read at 3281.61 MB/s and write at 2660.95 MB/s.

The 980 also performed fairly well when doing random reads and writes. In our tests, the drive was able to read at 346.11 MB/s and write at 667.32 MB/s.

According to Samsung, the 1TB 980 is capable of 500,000 IOPS when reading and 480,000 IOPS when writing 4K blocks. In our tests, the drive reached 88,603 random read IOPS and 170,807 random write IOPS. As with most drives, the 980 performed better at higher queue depths. With eight threads and the queue depth set to 32, it reached 499,804 random read IOPS and 401,526 random write IOPS.
