Hi, I'm looking to upgrade my hard drive (I'm down to a gig) and was looking at the following: Fujitsu Toshiba Western Digital They all have essentially the same specs, just wondering if one is superior to another. Also, there's a SATA Western Digital one, it won't work right? If there's a better retailer that'll ship to Canada, I'd like to hear about it too please. (Not TigerDirect, unless the price is really good, their shipping is high.) Thanks!
