[K12OSN] SCSI hard drive speed

I have upgraded as far as I can go for this year.  Performance is 
acceptable, except that more than 2 instances of thin clients running 
tux type or tux math bogs entire system down.  Everything else functions 
well.  Staroffice and FireFox running simultaneously on 25+ machines 
doing research essays perform well enough for our school's needs.

For next year, or next term if I am lucky, I am thinking of upgrading 
the hard drives.  Currently using an old IBM SCSI drive (9gb) for /root 
and a Seagate SCSI (18 gb and 5400 rpm) for /home /opt and /swap.

Would 11000, or 15000 rpm SCSI drives show any kind of performance 
increase?  Even if they don't I would probably still upgrade them 
eventually to gain more storage anyway, but it would be nice to justify 
the bigger drive(s) by saying that the increased rpm would make a 
noticable improvement in performance
