raid – stay striped or unstripe?
Hi – we have 3x 500gb drives strped Raid 0 in a Macpro for FCP editing, I striped them for speed but having recently lost a LaCie FW drive am getting nervous – I know RAID 0 is fastest, but if you lose one drive, you lose all the media on all the drives… if I copy all the media to a backup drive, I assume I can un-stripe them, ie use them independently – will I see a speed drop in FCP? (It runs fantastically)

If you’re editing in DV (25 Megabits/second) then a RAID is not important. Each of those internal SATA drives is plenty fast enough. If you’re planning to edit in higher data rate formats such as 8-bit uncompressed then you’ll need the speed of the RAID. I backup some data from my RAID to inexpensive FireWire drives that I keep powered down after the transfer.

Depends on the codec your using, and if you’re doing multiclip, etc. I use a plain old FW800 500GB LaCie on my QuadCore G5 with DVCPRO-HD 720p24, and I have no problems. If you’re doing HDCAM SR or some other higher end codec, you may have to go with a RAID. There are other forms of RAID that stripe you could use. But it’s for swaping out drives going bad, not a full back-up system.
If you’re worried about losing data, you should have a dedicated back up system in place. Hard Drive, Tape Drive, DVD, whatever. Dedicated back-ups are NOT replaced by Stripe in a RAID array.
I’ve seen stripe RAID arrays go bad over the years, with very little recoverable data.

You have not told us why you think you need RAID, which is a misunderstood technology, often upsold to gullible video people.
see this site for some helpful explanations on the various RAID types.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”
