New set of harddrives? Caviar Black?

[note235]

Right now i have one caviar blue 640gb
was wondering if i should pick up a pair of caviar black 640gb to go along with it or get one 1TB black?
could i raid blue and black?

I wouldn't mix and match models like blue and black for raiding. It's generally better to have 2 fairly closely matched drives.

Two 640GB Black's stripe raided would be faster (though have a higher chance of failure) than a single 1TB Black.

hmm idk if ill use raid that much?
the things i have are in physical storage (minidvs)
so if i dont raid would 1 TB be better as it is cheaper?

I would.

If you are not going to be using RAID much, why spend more money on a smaller drive? If storage is what's important to you and/or money get the 1 TB. Even if performance is something you desire, I have read that RAID has negligible real world effects. Here's a review (http://www.anandtech.com/storage/showdoc.aspx?i=2101) of RAID by anandtech if you would like to read more.

You also have to think why you want to RAID in the first place...

Well I wanted a partial backup

RAID is not backup, nor will it ever be. It is a protective measure against physical disk failure.

oh okay
thanks

If you are talking RAID 0, and I assume he is, it's not even a protection against disk failure, it's an increased risk.
