New laptop has a usb3.0 port. I'm wondering if anyone has experience using an external usb 3.0 drive as a recording drive. I would be using a drive enclosure with a purpose spec'ed drive for recording, 7200 RPM and a big cache, and a fast write speed - something like this: http://www.microcenter.com/product/431318/Se_1TB_7200_RPM_SATA_60Gb-s_35_NAS_Internal_Hard_drive_-_WD1002F9YZ

A couple of questions, does anyone have experience using a USB 3 external drive for primary recording/playback?
Do I need to go for a 6 Gb/s transfer rate if USB 3 isn't really up to snuff?
