Now we have the results provided by HD Tune program.

Here Western Digital VelociRaptor and Hitachi Deskstar P7K500 achieved a similar burst transfer rate, with Seagate Barracuda 7200.11 and Seagate Barracuda 7200.10 being very close. These disks were, on average, 9% faster than Hitachi Deskstar T7K500 and Samsung HD322HJ – which achieved the same performance level –, 22% faster than Western Digital Caviar SE16, and 55% faster than Western Digital RE2 and Western Digital Caviar SE, which achieved the same performance level.

Here Western Digital SE16 (16 MB buffer) was 29% faster than Western Digital SE (8 MB buffer).

The most important figure for most people is the average transfer rate. Here Western Digital VelociRaptor and Seagate Barracuda 7200.11 achieved the same performance level. They were, on average, 10% faster than Samsung HD322HJ, Western Digital Caviar SE and Western Digital Caviar SE16 – which achieved the same performance level –, 53% faster than Hitachi Deskstar P7K500, Seagate Barracuda 7200.10 and Western Digital RE2, and 67% faster than Hitachi Deskstar T7K500.

Samsung HD322HJ, Western Digital Caviar SE and Western Digital Caviar SE16 were, on average, 39% faster than Hitachi Deskstar P7K500, Seagate Barracuda 7200.10 and Western Digital RE2.

As explained before, the maximum transfer rate is achieved when the hard drive is reading data from its outer-most tracks.

Here we have different results from what we’ve seen on DiskSpeed32. Seagate Barracuda 7200.11 and Western Digital VelociRaptor achieved the same performance level, which was, on average, 9% higher than the one achieved by Western Digital Caviar SE, Samsung HD322HJ and Western Digital Caviar SE16, 57% higher than the one achieved by Western Digital RE2, Seagate Barracuda 7200.10 and Hitachi Deskstar P7K500 and 68% higher than the one achieved by Hitachi Deskstar T7K500.

As explained before, the minimum transfer rate is achieved when the hard drive is reading data from its inner-most tracks.

The results here confirmed what we’ve seen on DiskSpeed32: Western Digital VelociRaptor is the hard disk drive with the highest minimum transfer rate, meaning that it will still deliver a decent performance even on worst-case scenario.

Here Seagate Barracuda 7200.11, Samsung HD322HJ and Western Digital Caviar SE achieved the same performance level.
