I am looking for a 250GB external hard drive. There are about 8 different makes/models out there all with pretty much the same specs (8MB buffer, 7200 speed) and a price differential of about $100 (between appx $240-$340 - LaCie, Maxtor, Acomadata, Western Digital, etc, etc.) besides the fact that some weigh slightly more than others, some are USB 2 rather than firewire (although some are both) and they have different colored cases, does anyone suggest one that is best?
