The last I checked, USB 3 external SSD HDs were expensive and newegg only lists two. The ASUS motherboard that I used in this PC I built has a USB 3 boost feature for speeding up data transfer rates (yes case has USB 3 ports). Also the PC's lone HD is a SSD. Couldn't I purchase a SSD and an external enclosure featuring SATA III and USB 3 (they are around $25 at newegg) and make one or am I missing something? This would be used for imaging weekly or whatever. Thank you!
