So I've got two 500GB HDs...

[Raapys]

Also, you guys seem to be missing the fact that most people want the biggest possible amount of disk space these days. For most people I know, there's no way they'd sacrifice 500gb of space by going Raid1 just to possibly avoid the consequences of a disk failure.

This is how I think it should be done: Put two smaller hdds in a Raid0 array and then install windows and all your applications and games onto that array. This will let those programs take advatange of the great performance of Raid0. Then you simply use a regular hdd of some size for storage; put all your documents, movies, save-games, porn, whatever, in there.

Should the Raid0 array ever fail, it's simply a matter of replacing the broken disk and reinstalling windows and your games and applications. All the important stuff will still be stored on your storage disk.
