AS SSD:
AS SSD is a relatively new benchmark designed specifically for solid state drives. The application contains five synthetic tests used to determine the sequential and random read and write performance of a drive. Take note that AS SSD uses incompressible data in its tests, which can have a major impact on the scores of SandForce-based drives like the RevoDrive 3.
AS SSD also includes a copy benchmark. This test copies an ISO (two large files), program (many small files) and game (small and large files), returning the speed and duration of each.
HD Tune Pro 4.61:
Next, I ran a series of tests using HD Tune Pro. This hard disk utility measures a drive's performance by testing its sequential read and write speeds as well as its access time, burst rate and CPU usage. For this review, I'm also going to use it to benchmark the RevoDrive 3's random read and write speeds, random access times and the number of operations per second.

The RevoDrive 3 performed very well when benchmarked with HD Tune. The drive had average read and write speeds of 844.4 MB/s and 718.2 MB/s, respectively, and a burst rate of 328.1 MB/s when reading.

The RevoDrive 3 didn't disappoint when doing random reads and writes. When writing 4KB blocks, the drive reached 21758 IOPS and had an average speed of 84.992 MB/s. The RevoDrive 3 was even faster when reading, reaching 23531 IOPS with an average speed of 91.918 MB/s.
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 RevoDrive 3's read and write speeds and the number of operations per second. The tests were run using both repeating and random bytes and a queue depth of 3.
The RevoDrive 3's performance was very similar to what we saw in our other tests. With highly compressible, repeating data, the drive was able to read at 938.44 MB/s and write at 824.96 MB/s. When tested with random data, the RevoDrive 3's read and write speeds dropped to 359.74 MB/s and 154.89 MB/s, respectively.
The RevoDrive 3 performed quite well when doing random reads and writes. With repeating data, the drive was able to read at 50.9 MB/s and write at 296.59 MB/s. Here too, the RevoDrive 3 took a performance hit when tested with random data. However, it was still able to write at 146.07 MB/s.
According to OCZ, the RevoDrive 3 can deliver a maximum of 120,000 IOPS when randomly writing 4K blocks. In our tests, the drive reached 75,926 IOPS with repeating data and 37,395 IOPS with random data. This by itself is impressive. However, with the queue depth set to 32, the RevoDrive 3 reached an incredible 121,828 IOPS.
