Looking For Back Up Drive - 2 - 4 Gig - 7,200 RPM - USB 3 - Windows 7 - PC

I am looking for a back up drive between 2 - 4 gigs, USB 3.0 connectivity, 7,200 RPM (don’t want 5,400 RPM drive), to back up desktop PC running Windows 7.  Does WD offer such a drive?  If so, what model?

I guess you mean 2/4TB instead of 2/4GB? You might be interested in the My Book Essential line of external desktop drives. They are available in 1 to 4 TB capacity, have USB 3.0 connectivity. They also support our free backup solution software called Smartware. For more information follow the links below.
