Frankly, 4x4x6x is painfully slow. The drive is clearly an internal EIDE device with a USB interface, wrapped in a silver metal casing.
Construction is a little flimsy, but still acceptable.
There's also an emergency eject hole. The drive also has an external power switch, which should reduce worries about a barbecue spontaneously starting overnight. Naturally, a USB cable is supplied, and installation is hassle-free. The Acer is supplied with Adaptec's previous generation Easy CD 4 and DirectCD 3 software, which is good, solid stuff. Not thrilling, but no complaints either.
