The reader is actually a Express card removable module on my ThinkPad T430s.
On the others, I'm aware of the *rated* speed, and I certainly see the value of 1000X vs. 400X on the readers. I'm just a little surprised how close they were on the old USB 2.0 reader vs. new USB 3.0.
Looking at the wikipedia page, USB 2.0 should be capable of 60MB/sec. (theoretically) and USB 3.0 should be 625MB/sec, so it does seem like there should be some difference on the 1000X cards.
I'm also on a pre-production T430s, so maybe I need to update the drivers... I'll do that and report back.
now expresscard uses either PCIe or USB2 for a path that is decided by the maker of the module using the slot.
