[an error occurred while processing this directive]

The Deskstar 75GXP's stratospheric areal density combined with its 7200rpm operation result in a sequential transfer rate in outermost zones of 37.2 MB/sec, the second-highest figure we've ever witnessed (2nd only to the SCSI Quantum Atlas 10k II).

The drive's access time measures in at 12.4 milliseconds, implying that the drive easily beats its advertised seek time. Ignoring overhead, such a figure indicates a seek time of 8.2 milliseconds. Not shabby at all!

So then, how do these blazing figures translate into performance? Read on!
