Vantec NexStar MX Dual 3.5" SATA Drive Enclosure Review
With internal hard drives getting bigger and bigger these days, that means the size of backup media is also going to have to increase. Of course the DVD method is great, but when your backing up a hard drive it can become an incredibly time wasting process to burn many DVDs.
