Mildly interesting, but probably hard to understand to lots of non-computer, computer users.
SATA RAID's are the coming thing, even for video community users. RAID 5 trades off BIG time for write speeds and RAID 0 gets faster, the more stripes you add.
A wise implementation would be, if no cost were the object. One set of RAID 0 disks, lets say 8 stripes which can aggregate nearly 550 MB/sec. Plenty of speed for capturing and editing. Another backup RAID 5 which writes at maybe 55-60 MB/sec on a 5 drive (stripe) set, to mid range archive important work to. Another con for inexpensive SATA RAID's is the fact that there is no controller smoothing out the data flow with disk caches such as used in the XServe RAID. SATA RAID stripes have one other major con, and that is as you get to about 2/3rds of the capacity of a SATA RAID your speeds start to slow down to nearly half of the empty bandwidth. To beat that, you mearly load up big drives to each stripe so that you never have to use the last 3rd for high bandwidth transfers.
Keep in mind that not many inexpensive solutions even offer a RAID 5 configuration and especially one that can self-recover after a failed disk drive. You are getting into the BIG BOYS area of cost with reduntant drives and power supplys.
With the soon coming 1.0 Terabyte 3.5" disk drives. it's gonna get crazy with storage sizes.
