if you really want speed, get several identical drives and data stripe them in a raid 
setup, this effectively multiplies the speed of one drive by the number of drives you 
have after the first track is found.  the idea being that the data is spread amongst 
the drives and they all look for a piece of it at the same time and are all pumping 
data during a file transfer.  as far as getting drives, i'd get some with an sca 
connector on ebay, and look for a surplus sca backplane.  beyond that, check the specs 
for seek time, buffer size, and maximum transfer rate, and do buy a wide scsi card.  
you can also set up a raid so that the same data is on more than one drive in case a 
drive dies, and i think you can still do striping then as well, though most people 
don't need the backup it's good for big engineering projects, servers, or banks etc.

i've got some back plane sca boards that accommodate 6 drives each, they just need an 
enclosure and power supply and then just one cable to the computer, all the other 
connections are taken care of on the backplane board.  i haven't set it up yet, but 
when i get some money i plan to buy a stack of identical drives on ebay and set up a 
big raid file server on my fastest machine and serve files to the other machines over 
ethernet.  this way you get truly huge storage for all your machines and really high 
speed on your main machine, which ideally will connect to a 100bt or gigabit ethernet 
switch for the other machines (though i'll probably just go 100bt, most of my machines 
aren't that fast and i don't think there's a lot of gigabit stuff surplused yet).  

as much as i'm starting to hate ebay more and more (they've absolutely no clue about 
security and really don't care about scammers as long as they get their money...) it's 
the place to get drives cheap, often new.  there are several listers selling boxes of 
new scsi drives that are fast and wide with an sca connector.  the sca backplanes i 
have are surplus from compaq servers.   if you're interested i'll try to look up who i 
bought them from, they were inexpensive and are well made, including slots for 
airflow, though i did get them a couple of years ago (the last time i had money, but i 
never got around to getting a stack of drives, just as well as larger ones are 
available cheaply now).  the sca backplanes also use standard pc power supplies, and 
have connections for 2 of them if you get redundant supplies.  the backplane even 
takes care of setting the scsi id.
