For some, a simple USB thumb drive is not enough portable storage, even at its largest capacity. Whether it's for backup purposes or there's a need to carry gobs of data around, there is no better alternative to hard drive capacities. Retail external drive kits can be pricey, which is where Vantec comes in with their NexStar3 with eSATA Interface. This enclosure lets you drop in your own hard drive and make it as portable as can be. Married with the right hard drive, this package can offer sizeable external space along with excellent transfer rates.
