I'll third the vote for G-Tech. They're more expensive but worth the extra, who wants a HD that dies after a few months. WD and all the other cheap drives are pretty poor IMHO, useful to buy if your sending files or video abroad as a one off, but no good for backing up valuable stuff over time. The G-Tech drives come with built in weird Mac only formatting, if your on Windows you need to google around for advice on how to re-format to NTFS.
