X-bit Labs published a roundup of 500GB hard disk drives, you can check it out over here.
Far not everyone out there needs enormous hard disk drives. Many users out there feel quite happy with smaller HDDs for their systems storing most of their data on external media. And quite a few users do not really have that much data to store anyway. We hope our roundup of 3.5-inch 500 GB HDDs will be helpful for these particular users.
