Any new release on Portable external Hard Drive?

I am waiting for WD to release a portable hard drive that has more than 1TB. I was wondering if WD going to release something like that. Im eagerly waiting for it ever since 1TB was release i’m waiting for a 1.5TB or 2TB. Does anyone know when will they release it or if they are going to ever release it?


Can someone tell me how I can select a specific directory to perform a back up? or maybe how to select some extensions that are not in the list? . Besides I need to perform a backup for many Computers that are in the same network, I have an access point which has an USB port.
