OCZ Agility 4 256GB Review

Testing:

Atto Disk Benchmark v2.47: Atto Disk Benchmark is another aged, but good hard drive benchmark utility designed to test read and write speeds for different file sizes.

The read/write specifications for this drive are almost met in the read tests and exceeded in the write tests. The 4K write performance is just shy of the Vertex 4 and ahead of the Sandforce and earlier generation controller equipped drives at 305MB/s.
