Because I know I can count on friends like you to tell me about
nifty programs like bonnie :-)
The relevant results for /usr/sbin/bonnie++, as an ordinary user
with no command line options, for my SATA desktop (7200rpm), the
SATA T60 (7200rpm), and my old PATA T30 (5400rpm), in MB/sec, are:
DESK T60 T30
Sequential Block Read: 70.2 73.9 41.5
Sequential Block Write: 55.8 65.9 35.1
... and a derived number:
Read speed KB/RPM-sec: 9.754 10.257 7.684
The speed difference between the desktop and the T60 surprises
me a little, but the desktop uses a WD "green" harddrive that
may be suboptimal for Linux. Sure is quiet inside that sound-
dampened case, though, quieter than the laptop!
The main difference seems related to the drive rotation speed.
I'd be curious about other folk's results.

P.S. as an aside, the 500GB Seagate ST905003N3A1AS-RK notebook
hard drive ($90 from Frys) lists Windows, Mac, or *Linux* as
system requirements. No picture of Tux with the windoze and
mac symbols on the side, but a great first step nonetheless.
I guess they assume we can read ...
