I recently heard of these Hyperdrives and for shooting photos is would be a great asset since although I have 10 Gb's of CF card space going out on a shoot it is only approx. 750 photos (in RAW). That is fine while close to home but if I am gone for a day it is not going to be enough. So I am looking at getting myself one of these http://www.hyperdrive.com/ and would like to know if anyone knows of any alternative versions I may want to consider. I know of one other version and was not overly impressed by them, http://www.vistek.ca/details/details.aspx?WebCode=225459&CategoryID=StorageDevices If not I will consider the Hyperdrive model but would like options to consider.
