I'm in the process of ordering components for my soon to be media server and I have a few queestions. I'll be using a two 3Ware 7506-8's with a RAID 5 array containing 8 250GB drives on each card. I know the cards are 64bit cards and are backwards compatable to fit normal PCI slots. Will I gain any advantage using the 64bit slot or can I do fine with a regular PCI slot? Also can the 7506-8 run more than one array? As for the server case, is it really that much of an advantage to have hotswap drive cages?
