Here’s something you’ll find interesting.

While Mac’s don’t support USB 3 yet, USB 3 is backwards compatible with USB 2, which your Mac has.

So?

Well, USB 3 used in under USB 2 conditions (which I’ll call USB 3/2 to save typing) is much faster than USB 2.

For example, the ADATA S102/16GB USB 3 memory stick is about 50% faster than even the fastest USB 2 stick I’ve found.

And for more of a surprise, how about this:  the $19 Transcend USB 3 card reader (TS-RDF8K) is nearly twice as fast as my fastest USB 2 card reader (500MB copied in 11 sec vs 20 sec.)

So, if you’re into moving data from your camera faster, get a USB3 card reader even if your computer doesn’t support USB 3 yet.

As usual, however, YMMV.
