Oh, I should comment... and this is fascinating... I recently purchased a 32 GB SanDisk Extreme USB 3.0 memory stick. When I inserted it into a USB 3.0 port on my desktop PC, it showed up in Windows 7 as a SSD... not removable storage. SanDisk had put a SSD controller on the memory stick!
In my opinion, all permanent storage is going to start by-passing these various and unnecessary layers of I/O controllers.
