If by 'cable' you mean a cable modem providing at best a few Mb/s bandwidth, then I doubt the speed of your disk will have any impact whatsoever. Even the crappiest ATA disk will be able to deliver a few MB/s -- in the worst case that's still an order of magnitude more than you can stuff down your cable modem. On the other hand, on a 100Mb/s LAN you likely will notice the difference, especially if your server has multiple users. > Also, if the 5400RPM IDE HD was RAIDed, would that match an unRAIDed > 7200RPM IDE HD? Thanks in advance. Depends on what sort of RAID it is and what you're doing with it.
