I've been looking to add more storage to my Android tablet to play video, pictures, store files and more. However since many android tablets can't read a usb thumb driver or external hard drive by cable. I have found several devices including the Samsung Optical Smarthub, Seagate goflex satallite external hard drive and more to stream video, pictures and more via wifi. But two that have really peaked my interest is the Kingston Wi-Drive 32 GB USB 2.0 Portable External Hard Drive at $70 and the airstash for $115. I kind of like the airstash because its just about unlimited storage depending upon how many sd cards you have, but very expensive. Does anyone have any experience with these and do they? Recommendations?
