Reported random read speed of USB hard disk

By Mike | November 18th, 2008 | 7:08 am

The reported read speed of my attached devices at present are:

USB flash disk : 25843 KB/s  (approximately matches other speed tests I’ve done on it)

USB external hard disk : 1276492 KB / s (very high).

The external disk is a 750Gb Samsung 7200rpm desktop drive with 32Mb of cache.  I’m guessing that the speed test may be only using the cache and not the physical drive access itself.  However even if this is the case, I’m not sure how it can get a speed this high when connected by USB 2.0.  The maximum linear read speed I can achieve on the drive using USB is approximately 32000 KB/s.
