My goodness, it seems like there is no end to the size of a drive. Only yesterday an 80 GB drive was considered huge, but the demands of music, movies, & digital photography have driven the market to bigger & bigger drives & lower & lower prices.
In particular we favour LaCie, for their reputation, great service, extended warranty, & quick response to our customer issues & needs.
Western Digital is a company that brings innovation to the market place, plus their three & five-year warranties.
