I'm interested in hearing if people have experienced imporved transfer speeds with USB 3 devices, for both disk drives, and for reading compact flash cards.

On USB 2 devices, I've seen read speeds on disk drives at: 32 megabytes/second read, 26 megabytes/sec write, and 25 megabytes/sec read of compact flash cards. The disk read/write speeds are for linux; windows is somewhat slower.

Are people seeing better rates with usb3? If so, what hardware?

Windows 7 x64

Seagate FreeAgent GoGlex 1 TB (Blue :S3:)
Lacie USB3.0 PCI Express card

Aprox. values:
Read 78 MB/s
Write from 45 MB/s to 65 MB/s

I hope this helps.

ps: copying from/to a RAID0 array (2 x 1 TB Seagate Barracuda 7200.12)
