MacBook BootCamp Issues (USB Slow? Apparently not…)

Issue or Non-Issue?

  • USB2 port reportedly “throttled back” under Boot Camp:
  • My own measurements indicate there is no such issue:
    • 167Mbps when transferring a 75GB file from one USB drive to another, on a MacBook Pro.
    • About the same observed when repeated on a standard Windows laptop.
  • What should be expected in theory?
    • USB2 raw data throughput is 480 Mbps but throughput in practice is more like 300 Mbps.
    • When copying disk-to-disk, additional delays may exist. ¬†Googling around, a rate of about 1GB/minute (as per my measurements) doesn’t seem that unusual.
