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 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 990 EVO's performance was very similar to what we saw in our other tests. The drive was able to read at 4856.34 MB/s and write at 3611.52 MB/s.
The 990 EVO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 449.44 MB/s and write at a blazing 1146.03 MB/s.
According to Samsung, the 2TB 990 EVO is capable of 700K IOPS when reading and 800K IOPS when writing 4K blocks. With two threads and a queue depth of three, the drive reached 115,057 random read IOPS and 293,383 random write IOPS.
As with most drives, the 990 EVO performed better with more threads and at higher queue depths. With sixteen threads and the queue depth set to 32, it reached 767,334 random read IOPS and 686,017 random write IOPS.
