ATTO Disk Benchmark
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.
