RPM almost always does indicate speed, in that the faster a
disk revolves the faster the disk is positioned under the
head again to get more data. Now you could I suppose come
up with a strange enough system that extra speed wouldn't
matter, but that isn't the way most disks are these days.
Hmm. The www.ibm.com/storage web site should list all the
details on all the disks. When I have time I'll look there...
