Ubuntu's performance : how to speed up ?

[Vincent Trouilliez]

Okay, just had a look at Seagate's website.

Their current desktop drives ("Barracuda") do  7,200rpm 80MB/s, with an
avg seek time of 8.0ms  -> WOW, many times better than my existing
drive(s) !! :o)

Then I looked at their SCSI drives ("Cheetah")....  15K RPM -> transfert
rate 75MB/s but seek time of......   3.5ms !!!!!

Jesus christ, I want one... no, I want too, one for /usr and one
for /home !! :o)))

Will have to change me SCSI controller though, I have an old Adaptec
AHA-2940AU, I think it does only 20MB/s, maybe 40MB not sure, but not
more.
