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 990 PRO'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 990 PRO's performance was very similar to what we saw in our other tests. The drive was able to read at 7129.76 MB/s and write at a blazing 6549.12 MB/s.

The 990 PRO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 463.21 MB/s and write at a blazing 757.45 MB/s.

According to Samsung, the 2TB 990 PRO is capable of 1,400k IOPS when reading and 1,550K IOPS when writing 4K blocks with sixteen threads and at a queue depth of 32. With two threads and a queue depth of three, the drive reached 118,583 random read IOPS and 193,907 random write IOPS.

As with most drives, the 990 PRO performed better with more threads and at higher queue depths. With sixteen threads and the queue depth set to 32, it reached 922,035 random read IOPS and 715,502 random write IOPS.
