Western Digital – Velociraptor 600 GB Hard Drive

Crystal Disk Mark – 50 MB

The 50 MB file transfer mostly takes advantage of the burst speed of the hard drive (about 250 MB/s for this drive). The transfer rates for both modded capacities were significantly better than those of the full capacity. Sequential read reported a 22 MB/s gain while the sequential write reported a 12 MB/s loss for both capacities when compared to the original capacity.

Crystal Disk Mark – 500 MB – 4000 MB

500MB through 4000 MB showed similar results throughout all the tests. All of the results produced slightly better results in sequential reads that the original capacity test while all other results produced approximately 1 – 2 MB/s lower results than those of the original capacity. This can be mainly justified due to the fact that this test runs in a limited space provided by original parameters. This means that the advantage gained by short stroking the drive would not be as evident.

SiSoft Sandra – Physical Disk

Since SiSoft Sandra tests read speeds across the entire drive this test would take advantage of the short stroking. The results of this test corroborate those produced in HD Tune. The drive performed a 13 MB/s (average) better in the 300 GB test than the test using original capacity, and 6 MB/s than the test using 450 GB. The performance increases are also evident in the seek times. Velociraptor short stroked to 300 GB had faster seek times than both 450 GB and original capacity by 1.6 ms and 0.9 ms respectively.
