What to buy for a RAID 0

[hdvideo]

Ok Great thanks for the explanation.

What do i need to buy for a RAID 1 or 5 that is fast enough to allow me to edit HD footage?

RAID 0 provides NO protection against hard drive failure or pilot error, it is intended to speed up disk I/O by splitting the work between two drives. In fact, it increases the chance of data loss because the crash of a single drive will take out the entire array.

You want RAID 1 or RAID 5, or something above that.

HI,

I edit on newly upgraded edius 4.5 and love it so far.

My question is i current have 4 harddrives that i use for video storage as i edit projects. I have 3 250 gigs and a 150. 2 of the 250 gigs are internal satas and 1 250 and the 150 are external glyphs. The 150 glyph crashed a year ago but my data was recovered. The 250 glyph just crashed and hopefully i can recover that data as well. (the first time it crashed the computer could not read the index file on the disk, hopefully that is the same problem on the second)

What i would like to do is buy a couple more drives (external preferrably) and make them a RAID 0 configuration for the main purpose of when this happens again i don't have down time i just buy another harddrive and replace it.

What i need to know is what I need to buy. Hopefully they come raided because i don't know how to do this. I edit most things in HD so drive speed is important. I have been reading about the 1 gigabit ethernet raid stuff. Is this fast enough?

Thanks for your input in advance,

Brent
