We have a dell 2500 which has been lying about which weve decided to make use of. It has two hdd's: 1 4gb and 1 14gb. Obviously its not much good with this storage capacity so im looking to buy some new hdd's for it. I dont have any experience in server hardware so i want to know what type of hdd's are compatible with this server. The part number for the hdd's in it now are ST318452LC, theyre ultra160 80 pin scsi drives. My question is will any 80pin ultra320 drive work with this server? Can anyone fill in the blanks as to how this server hardware works?

Thanks alot in advance
