I just purchased a Seagate 3tb usb 3.0 External hard drive since I ran out of space on my Seagate 1tb usb 2.0. I will report a comparison once I get it up in running. I am looking forward to the speed boosts since 90% of my external is used for media streaming to my entire network
Here is what I have shipping from Amazon:
Seagate Expansion 3 TB USB 3.0 Desktop External Hard Drive
Syba 3 Port USB 3.0 PCI-e Card with 1 Internal Header
