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 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 512GB SSD 840 EVO's performance was very similar to what we saw in our other tests. The drive was able to read at 526.68 MB/s and write at 460.35 MB/s. With RAPID mode enabled, its read and write speeds jumped to 564.38 MB/s and 641.56 MB/s, respectively.

The SSD 840 EVO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 152.69 MB/s and write at 334.88 MB/s. This by itself is impressive, but with RAPID mode enabled, its random write speed jumped to 357.64 MB/s.

According to Samsung, the 750GB SSD 840 EVO is capable of 98,000 IOPS when reading and 90,000 IOPS when writing 4K blocks. In our tests, the drive reached 39,087 random read IOPS and 85,730 random write IOPS. RAPID mode had little impact on the SSD 840 EVO's random read performance. However, with it enabled, the drive was able to reach 91,557 random write IOPS.
