HD Tune / CrystalDiskMark / ATTO

Patriot results are shown on the left side with the Crucial listed on the right.

HD Tune shows a range of read speeds from 140MB/s to 193MB/s for the Patriot Torqx, with an overall average of 182MB/s. The Crucial C300 performs significantly faster, at an almost solid 280MB/s rate across the board. Even so, this is a good bit less than SATA 6Gb/s capability would suggest. We have seen mixed results from the free version of HD Tune in other recent tests, and it is quite a few revisions older than the current Pro version, so perhaps the benchmark itself is to blame.

CrystalDiskMark paints a slightly different picture. On the Patriot Torqx the sequential read shows similar results to the HD Tune, hitting 185MB/s. However the Crucial C300 blows away these speeds with a smoking 337MB/s sequential and an equally impressive 309MB/s 512K read. The write results of 144MB/s are right inline with Crucial claims for the 128Gb model.

ATTO Disk Benchmark reports the fastest speeds for both drives, almost 200MB/s read - 100MB/s write for the Patriot, and nearly 370MB/s read - 150MB/s write for the Crucial. This benchmark tests using files sizes from 500 Bytes to 8MB in size. Compared to other results, these may be slightly optimistic, particularly since they exceed the manufacturers' rated claims for their drives. However it does confirm roughly the same spread between the older SATA 3Gb/s drive interface and the new SATA 6Gb/s.
