USB 3.0 and SATA 3

Putting the Z77X-UD3H heads up against the Intel DZ77GA-70K in both SAT 3 and USB 3.0 speeds with the same SSD we are able to get a good idea of how there controllers perform. In this case with SATA 3 they are both almost spot on in performance. It was when we tested USB 3.0 that we saw a noticeable difference. With the Z77X-UD3H getting just over 20MB/s less in read speed over USB 3.0. Even with such a difference, the Z77X-UD3H’s USB 3.0 performance is worlds better than USB 2.0. I wouldn’t kick it out of bed for eating cookies, but if USB 3.0 performance is very important to you, there are other options that will give you better performance.

wm sata3

wm usb3.0
