That (500GB) would be RAID1 (mirroring). 1TB would be RAID0 (striping). The difference being that with RAID1 if you lose a drive you replace it and lose nothing. With RAID0 if you lose a drive you lose everything on both drives.
Right. Raid1. It will of course also do Raid0. I just haven’t decided if I’d rather have more space and periodically back up everything, or have less space but not worry about backup.
On the other hand, I’d probably back up a Raid1, in case a catastrophic failure corrupted both drives. So I’ll probably make it a raid0. Disks are pretty cheap, and I’ve got several USB drives sitting around.
My problem is two new cameras which have 12 megapixel resolution, and a family who loves to take pictures, but not to go through and delete the bad ones. We have over 36,000 pictures stored now. On a good day, I might get through a couple of hundred.
I have a different drive for videos. They are even worse. At least I’ve cut just about every video I have to a DVD by now. I’ve still got I think one old VHS tape left.
My next task is to take all the DVDs and get them back on a hard drive (I only have my digital camcorder stuff on hard drive, the rest was 8mm DAT which I did direct-to-DVD, and for which I no longer have an 8mm reader). I have a backup hard drive that plays direct to TV, so I need to get my DVDs onto it.
I remember being excited to get a 20 meg drive.
