Yes a 2.0 will work in a 3.0 port. And yes to vice versa.
Advantage of 3.0 vs. 2.0 is a massive upgrade on transfer speeds. USB 3.0 is capable of transfer speeds of up to 5Gbps (gigabits per second); that's a little over 10 times faster than USB 2.0's 480Mbps (1,000Mbps equals 1Gbps).
Of course, it will only run this fast if you stick it in a 3.0 port (as I'm sure you knew that ). And no, USB 2.0 doesn't run faster in a 3.0 port.

Also note that just because the USB interface is theoretically capable of transfers up to 5Gbps doesn't mean the flash drive can actually deliver 5Gbps of data.

Even on USB 2.0 ports, these drives are somewhat slow. SanDisk drives always seem to be.

FYI its $36 at Amazon now if shipping/tax is too much.

Yes, they are quite slow. Plus it looks like the ancient 64mb Pen drive I first owned.
