I have a friend who fried an external 1TB HD (connected to a Mac) which was used to store video files that they were editing.

Are there any specifications that would describe how to create a basic file server on a limited budget? My thought would be to use a old PC tower case and add in some sort of basic RAID controller with a series of harddrives.

If you're just worried about problems from wearing out your disk again, you can get a plain old external disk enclosure for around $50 that supports 2 mirrored disks (disks not included). This protects you against a single disk failure.

Update to answer the comment:

The key thing you're looking for here is support for RAID 1. I couldn't image ever buying a single disk enclosure any more, unless you're really concerned about portability or have a separate real backup solution (RAID 1 is not a real backup).

You can also search for a NAS (Network Attached Storage) device. These will come with disks and are likely easier to set up.

What would the enclosures be called? Who would carry these enclosures (ie TigerDirect)? – John M Feb 23 '11 at 17:27
