I think there are two standards for USB 3.0: low power (150mA) and high power (900mA). I cannot find which are used in SP3/dock...
I'll just mirror what you said swapping Seagate and WD. Seagate drives are always slower too.Picked up a Seagate slim (as I've had problems in the past w WD).
Works perfect on the SP3
