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.

Depends on what sort of RAID it is and what you're doing with it.

HTH,
