USB 3 on a Mac
Authored by: shavenyak on Dec 19, '11 09:48:10AM

Newer products which support USB 3 are probably using faster disks or faster flash memory to reap the benefits of USB 3's faster bus, whereas older products that were always going to be constrained by USB 2 anyway wouldn't have gotten enough extra performance to justify the higher-priced components.

It's all academic to me, though, because my main "Mac" does have USB 3. ;)

This is probably accurate, yeah. When dealing with anything, you always have multiple bottlenecks.

USB 3 on a Mac

I was going to agree with you here, but then I started to wonder... the OP says his USB3 card reader is almost twice as fast as his USB2, and I would assume that test was done with the same flash memory in each one... I know the hardware in the drive also affects the speed of accessing the card, but I would not expect this much of a difference.

I also remembered that I was looking at the System Information window on my iMac the other day and it did show that the drive I was looking at was a USB 3 device, so I wonder if that might mean the computer is using some improved driver or something even though it doesn't have all the hardware that it needs.

I admit I don't know much about hardware, and your explanation sounds the most logical, but I still have to wonder...
