Testing Desktop Hard Drives (Introduction)

Last updated 2009-06-01 - Send Feedback
Related: hard drive, storage

This area shows technical test data for high performance hard drives eg 3.5" desktop models for use in the Mac Pro and iMac.

Testing is done using DiskTester, the de-facto standard for testing hard drives on the Mac.

DiskTester yields an overall performance characterization of a hard drive, RAID, or even a network drive. However, for any particular purpose, a drive might or might not be the best performer. A good example of this is the Hitachi Deskstar 7K1000, which tests on the slow side, but shows excellent performance in a 2-drive eSATA RAID stripe on the MacBook Pro.
