The Vantec NexStar 3 SuperSpeed delivers exactly what it promises. You get the performance advantage of USB 3.0 over the 2.0 standard along with the plug & play ease of use we have come to love from the universal serial bus. It manages to deliver the maximum performance of the installed hard drive just like eSATA would, but with the advantage of a solid hot-swappable standard instead of somewhat flaky "will this work without a reboot?" implementation of the external SATA connectivity. That said, USB 3.0 is still in its early stages and mainboards are pushing the standard nonetheless. Vantec is showing that they are ready with new products, but until the enclosures come down in price - which is certainly not the manufacturer's fault - they do not have the price / performance ratio of affordable eSATA enclosures. If you are looking for a future proof investment which works on your current USB 2.0 as well as the USB 3.0 once it is available to you, the Vantec NexStar 3 SuperSpeed is a solid choice.
