any info on CPU load ? USB 2.0 used to be very heavy on the CPU, moreso with some USB chipsets than others. Is 3.0 any better and more consistent ?

What about latency?
I can't think of many compelling uses for the extra speed, given storage is covered by eSATA.
But latency has been a problem with USB 2.0, preventing good USB audio devices. Is that improved with USB 3.0?

Newer large (16+GB) USB flash drives?
SDHC card readers? I have a 32GB SDHC for my digital camcorder. I sure would love USB 3.0 for downloading the content.

The latency in USB 3.0 and 2.0 is due to Windows's Operation Systems after Windows 2000. It considers transfers of less the 64 Kb control transfers, and these kind of transfers has error cheking, that causes delay.
More informations about USB transfers in can be found at

A superior article, thank you for educating me! It is obvious that the USB 3.0 hardware interface has a ways to go before reaching it's potential. I have a USB 3.0 flash drive for use with my USB 3.0 support mainboard, and it is noticeably faster than USB 2.0 when copying files. But thanks to this article, I know that it's speed could be, and should be, much better.
