I’m running Vista Home Premium, SP2, Intel Core Duo 2,13GHz, 232 GB H/D capacity and 2 GB RAM.

I have a gift certificate for Best Buy and would like to put it towards an external hard drive for back up purposes. I’d like to stay in the $100 range. One Geek Squad rep said he recommends the smaller drives because they’re USB without an AC/DC adapter to plug in. They don’t have that many external drives in the stores so I could use the certificate on the web site. They only had one SATA drive in stock with the adapter plug in.

Also, I don’t shoot any video, just photos.

Is a USB drive fine or should get the larger one?

Any suggestions on good brands/models in that price range?

Thanks,
Mike
