You're probably right there, though I don't expect a lot of blackouts, so I'm not really sure whether it's worth it, plus PC components should survive some anyway (not a power surge though).
I'll probably get something similar in the future, but it's not something I consider terribly critical at the moment.

But with the case of Windows dynamic disks, there's also the problem of the computer crashing, causing a similar thing to happen.

Thanks for the advice though. :)
