Anvil's Storage Utilities:
Anvil's Storage Utilities is another new 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 SSD 840 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 512GB SSD 840 Pro's performance was very similar to what we saw in our other tests. The drive was able to read at 533.46 MB/s and write at 510.01 MB/s.
The 512GB SSD 840 Pro also performed very well when doing random reads and writes. In our tests, the drive was able to write at 163.26 MB/s and read at a blazing 337.13 MB/s.
According to Samsung, the 512GB SSD 840 Pro is capable of 100,000 IOPS when reading and 90,000 IOPS when writing 4K blocks. In our tests, the drive reached 41,795 random read IOPS and 86,306 random write IOPS. Increasing the queue depth had little impact on the SSD 840 Pro's random write performance. However, with the queue depth set to 32, the drive was able to reach 98,484 random read IOPS.
