But for video editing before the encoding process, sure thing. But I dunno how useful it is for stuff other than that, really. "But, game load speeds should drop!" - yeah well, I put the entire of "Thief 3: Deadly Shadows" on a RAM disk, which is plenty faster than the fastest RAID stripe you can muster, and that didn't do anything for game load speed. And seek-time can go up when using raid. And then you have the "all data dead on single drive failure" aspect of STRIPE... ugh.
I don't agree that RAID MIRROR is too much hassle for home setups, and you shouldn't be comparing it to backups - those are two entirely different things. A mirror won't help you against stupid accidents or malware, a good backup solution can do that (if you disconnect the backup location once done). At the other hand, if you only backup once per day, you risk losing a whole day's work if you don't have a mirror.
RAID MIRROR and a proper backup strategy goes hand in hand, really. Oh, and a decent RAID MIRROR solution will give about the same write speed as a single drive (possibly a slight bit slower), but give about double the read speed (ie, you get striped reads). Iirc Intel RAID Matrix storage does this, nvidia's NForce4 certainly doesn't (my mirror back then was noticably slower than a single disk, for reads as well as writes >_<).
Btw., with a RAID-STRIPE setup I did find that things like extracting big .RAR archives with same source and destination went a lot better than on a single disk (ie., handles "stressful workloads" better than a single drive), but still worwse than having distinct physical disks for source and destination.
