For example, IBM's Deskstar 25GP and Deskstar 22GXP list the sustained data
transfer rates as 15.5-8.7MB/sec and 17.9-10.7MB/sec, respectively. Nowhere
near the theoretical maximum of the UDMA/66 interface, or the UDMA/33
interface, for that matter.
Methinks people are expecting too much from these drives without knowing the
real specifications (and limitations).
