Hardware, Embedded Systems AMD plans to start shipping the USB 3-equipped chipset in the fourth quarter of 2010, beating Intel to the post. Intel hasn't announced its official plans for integrated USB 3 support yet, but various sources say it's not expected until we're well into 2011.

I consistency get around 29MBs with external hard drivers (Both read and write).

Flash drives seem to get around 29MBs read and 15MBs write.

One short coming of USB seems to be when all CPU's are fully loaded, throughput decreases.

I wonder whether the hard disk is limited because of something to do with Mac OS X and how it handles USB and/or FAT file system - funny enough when I convert it over to HFS+ the throughput improves but it still isn't close to that of the Windows world so are there issues relating to how things are handled on Mac OS X? is there a weigh up between conserving power and throughput given that power management is baked right into the I/O Kit where power management is automatic rather than the driver developer manually regulating power management.
