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 QVO'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 QVO's performance was very similar to what we saw in our other tests. The drive was able to read at 533.04 MB/s and write at 483.79 MB/s.
The 870 QVO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 199.84 MB/s and write at an impressive 342.08 MB/s.
According to Samsung, the 1TB version of the 870 QVO is capable of 98,000 IOPS when reading and 88,000 IOPS when writing 4K blocks. In our tests, the drive reached 51,158 random read IOPS and 87,574 random write IOPS. Increasing the queue depth had little impact on the 870 QVO's random write performance. However, with the queue depth set to 32, the drive was able to reach 97,397 random read IOPS.
