RAID-0 or other setup for speed AND data safety?
Have been looking into alternative storage solutions for my graphics station, using a Decklink Pro for uncompressed SD…
A 2 or 3 x SATA RAID-0 setup has been suggested and a sep drive for OS/apps.
Talking to our IT guy about this setup, he has warned me that RAID-0 would mean full data (video) loss if one of the drives went. This is no good obviously! Though talking to many AE/Premiere, etc users on the COW it seems many use this RAID-0 setup. How do people make sure their work is safe from drive failure then?I need a solution that gives me improved read/write speed for capture & playback, but also a constant backup for projects/assets/footage.
I currently run 1 x 110gb IDE system drive and 1 x 80gb SCSI media/client drive, both internal. Obviously 80GB is nowhere near enough for video, but I mainly work on stills at present and I currently backup all my client files onto the system drive on a nightly backup file.
I will soon be working with more footage and storing it locally so need a bigger, faster storage solution but one that protects me from drive failure. I will probably winrar footage and backup individ projects onto DVD-R for archiving every week or so, but need protection inbetween.
What are my best options in people’s opinions? I’m looking for about 500GB storage (7200rpm drives) and ideally spending under

If you are shooting onto tape, that is your backup. That’s why only footage goes onto a RAID 0 system; project files, graphics, etc., go on a RAID 1, 5, or similar redundant system.
If you are not using a camcorder with tape (P2 perhaps), I’d suggest a bunch of FireWire drives to archive to.

Hi,,
If you are really bothered about your data safety go for a raid 5. sata raid solutions nowadays are quite cheap and give quite good performence and are reliable. remember with raid 5 you will get approx the speed and space of n-1 drive. so for a 4 drive setup you will get to use space of 4-1=3 drive only.
just make shure your disks doesnot get too hot. this will give you a long life to your disks and raid.best of luck

Thinking it through I think I will go for an SATA RAID-0 of 2x250gb disks for source footage/renders and then my 80GB scsi drive for projects/PSD’s, etc. then I would have a backup set up for my scsi>system drive every night.
Does that sound like a good workflow?
Going RAID 5 would mean extra drives and a new motherboard that supports it, which is not really viable, as this system I am building up will probably be redundant (or used as a back up SD system) in a few months when we go HD anyway.
My current board only supports software RAID 0 – which has got me thinking…I hear that software RAID can put a strain on the CPU and my CPU is right on the cusp of min spec as it is – will this s/ware RAID make my system go bonkers?
Thanks for your help guys.
