I actually use one of these drives hooked to my Airport Extreme router by USB for my Time Capsule backups.
Most of my clients that have lost data have had no backup at all or the backup software failed and no one knew about it.
When you say: "if you're looking for ... backup" -- that makes me nervous. The "if" word, to be specific, is what makes me nervous. I can tell from your post that you, personally, understand the issue. But please, let's all get in the habit of saying; "RAID is not backup." Everyone needs to hear that more often. Raid only protects you from *one* of the big 'Oh-oh's':
1. Oh crumbs! My hard drive seized up. RAID is good for that.
2. Yikes! The power supply (or mobo, or raid controller... ) died during a write and scribbled nonsense on both drives. RAID won't save you.
3. Oooops... I wish I hadn't deleted that. RAID won't save you.
4. Crikey.... I must have deleted that file over a week a ago.... neither RAID nor last night's backup will save you.
5. Waaah! My house/business burned down (or smoke alarm set off the sprinkler system) and took all my customer data with it, along with 5 years of tax data. Only the off-premises backup can save you now.
Oh... and just for good measure, I found out a few weeks ago that it can be bloody hard to move a RAID set from one Linux system to another unless *every* little thing about software versions, etc, that you compiled into the kernel are absolutely identical. Thank heaven for tarball's.
