A "Raid array" is multiple hdds (two or more) on a controller card, (or in
software via NT)... There are different way to build an array... Mirror is
the most common as it's basically two drives with one being an exact copy of
the other... It's mainly used for servers... That way if one drive fails, it
will use the other one without so much as a hitch, and you can just plop a
new drive in, and the server never stops for downtime.
The other type of array (the one I use) is known as "Stripe" .  It basically
takes two (or more) drives, and splits the data sent to them up, thereby
doubling the performance of one drive. The drives show up in your OS as one
large drive... thus two 20 gig drives look like one 40 gig drive in
explorer. I use a Promise FastTrak PCI bus mastering controller card for
this feat... here is the website: www.promise.com
Video editing is extremely demanding on HDD performance, and size... It
takes a very...very fast HDD to capture video with some video cards... My
Miro DC30+ can transfer data as fast as 7mb/sec *sustained* to the HDD...
That may not seem like much, but I tried it with only one of my 20 gig 7,200
rpm drives just to test it, and I got dropped frames in the video.... The
drive couldn't keep up!... But _two_ drives on the FastTrak can take all I
can throw at them... I had a  10,000 rpm UW scsi drive about a year ago, and
on large capture sessions (as it got hot I suppose)even it would drop a
frame here and there.... Not so on my Raid array.

I hope this helps!
