I have a 4400 Poweredge server from Dell. Currently it has four 9 gb drives and we are looking to upgrade to four 36gb drives. Through Dell the price is $249 a piece, I have found other drives that are cheaper, but need advice on what brand to buy for compatibility issues as well as the lowest price<----I know this may sound a bit like an oxymoron, but I'm just trying to save the company a little money, we're small, ya know. I'm running a ACPT x86 Family Model 8 Stepping 3 processor, and a Dell Perc3/Di Raid controller, with 523,816 kb of RAM, not sure of origin of RAM. Any help would be appericiated.
