Yes, it does have USB 3 speeds,
Verified Purchase(What is this?)
This review is from: CPO 2M USB 3.0 Extension Cable, Male to Female - Black and Blue (Personal Computers)
Bought this for the WD My Passport Essential (which btw, has a ridiculously short proprietary cable). I get reads/writes of 60-70MB/s so I can conclude that the cable works.
Guess that's all you wanted to know really!
