4-Way SSD Round-Up Redux: OCZ, Corsair, PhotoFast

ATTO Disk Benchmark

ATTO is a more straight-forward type of disk benchmark that measures transfers across a specific volume length.  It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart.  We chose .5kb through 8192kb transfer sizes over a total max volume length of 256MB.  This test was performed on blank, formatted drives with NTFS partitions.

ATTO Disk Benchmark - Read/Write Performance
Version 2.02

   
OCZ Vertex Series 120GB

   
OCZ Vertex Turbo 120GB

 
Photofast G-Monster V5 256GB

   
Corsair P64 64GB

As you can see, none of the solid state drives we tested really hit their stride until transfer sizes exceeded the 64kb mark. Once again, the Photofast G-Monster V5 came out on top in terms of average read and write scores here, that come extremely close to its advertised 270MB/s. The OCZ Vertex drives offer similar read performance (260MB/s+), but in terms of sustained writes they can't match the G-Monster. The Corsair P64 put up some respectable read and write scores of about 220MB/s and 163MB/s, respectively, but the other drives finished well ahead.
