OCZ Agility 3 240GB SATA 6Gbps SSD Review – Preliminary Benchmarks


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications.  For our testing, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb.  Manufacturers prefer this method of testing as it deals with raw data rather than random or mixed which, although more realistic, result with lower performance results.

The high sequential scores of 555MB/s read and 473MB/s write are just about dead on to the manufacturers listed specifications.


Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill) or random data. We elected to test with random data in this case as it bests shows the difference between the Agility 3 and the Vertex which will also be shown with AS SSD.  The Agility 3 can be seen on the left with the Vertex 3 on the right.

In examining the all important low 4k random scores as well, we can see the difference between the Vertex 3 and Agility 3 as the Vertex 3 had an amazing low 4k random result of 100MB/s compared to the Agility 3 result of 85MB/s.  This is still an excellent result by the way.


AS SSD Disk Benchmark is perhaps the only benchmark program that was created for solid state drives.  Once again, lets do a comparison, this time including IOPS with the Agility 3 on top.
