The 11inch air only has 128GB and i'm getting short on space. Since the mb air only has 2 usb ports and no firewire or ethernet ports I'm stuck with the bandwidth of USB 2.0. I need 1 or 2 HD's for my audio and video editing so they need to be fast but it couldn't hurt if it looked nice and fits in my back pocket. Any recently Flash drives out there which is worth to take a look at? Thanks!
Most hard drives will be limited not by the hard drive itself, but by the speed of the USB interface. So almost any small (2.5") external hard drive will have the same speed (in terms of large sustained reads and writes).
