Re: External PC hard Drive Setup
I bought a 500GB USB drive a month ago, using it for backups. I have a smaller USB hard drive enclosure that I put a 30 GB EIDE drive in. I use this for moving files and to back up critical files.
Watch the sales ads. Best price I saw for a 500 GB USB drive was Black Friday (Thanksgiving weekend) for about $90 -- forget what store it was at. My wife chose to get me something else for Christmas, so I kept watching... Got a different brand 500 GB at Office Max for about $119 less a 15% coupon, net $101.15. Since I'm not using it all the time, I don't think the brand is significant, although if you do, just keep watching for sales on Seagate or Western Digital. They'll be in that price range, too. You can also check out buy.com, newegg.com, etc.
One thing I don't do that I should, is to keep a backup offsite. Maybe I'll start doing that...
