Windows 7: Double-speed USB 3.0 to arrive next year

Windows 7 Ultimate x64 SP1
 
 

Gives me an excuse to wait adding a PCI-E USB3 expansion card into my machine. :P

I have an HP Windows 7 desktop I just bought in September that has a couple USB 3.0 ports. Don't know how the speed measures but it's a LOT faster than 2.0. Really nice if you're moving a bunch of photos, etc.

Yeah, it is faster than USB2. But eSata is even faster.

I have a desktop with USB3 and eSata and when I make images to the same external disk to either one, the images go faster on the eSata although the specifications would not suggest that.

I imagine eSata has lower latency ir something.

Thunderbolt is also significantly juicier, as you can daisy-chain 10 or so stuff and still get pretty high speed anyway since it uses a better protocol. (within reason, of course)

eSata is the same as if it was internal, as it is just cosmetically different from a normal Sata port on a mobo. Can run circles around USB 3.0 anytime, anywhere as it has a lot less overhead sot it is much closer to its theoretical max speed than USB 3.0.
USB 3.0 has power though, while eSata does not. (well there is eSata power that steals the power from a USB port, but it's rare)
