External storage devices in Photography Gear and Technique Posted June 29, 2009 I'm an It Professional and a bit of a gadget freak, so have to say what a nice unit this is!! What a sweeeet device the Colorspace UDMA Card Reader is! So freakin' fast! and it rune almost forever on a single AA Li/Ion battery. I went 2 weeks without recharging and this little nugget didn't have a single glitch! Kudos to the Hyperdrive folks!
