Section 6. Frequently Asked Questions
Q: What are the transfer rates for the different interfaces?
A: Different interfaces have different maximum transfer rates. The following
table compares the transfer rates for the different interfaces.
Interface
USB 2.0 (Hi-Speed)
USB 1.1 (Full-Speed)
IEEE 1394 (FireWire)
Actual transfer rates in the real world depend on the type of media and
software you're using, and on the type of data being transferred.
Q: Can I get USB 2.0 on a Macintosh?
A: The Macintosh currently has USB 1.1 built in. If your Macintosh has a
PCI slot, you can purchase and install a USB 2.0 interface card. However,
any OS below OS X does not have USB 2.0 support, so you may also have
to upgrade your Mac operating system. If your Macintosh lacks a PCI slot,
you should use the FireWire port, if available.
