No actual industry facts for this, but I think the Flash used in thumb
drives are not really any slower by nature/design. This is because I
see that the fastest SSD currently tend to use 8 channel controllers
for 200+ MB/s performance which translate to 20~30MB/sec per channel.

The better USB 2.0 thumb drives can do about 20+ MB, Kingston even has
a new one that will supposedly do 70+ when connected via USB 3.0. If
we take 8 of these and RAID 0 them which is pretty much what the
8-channel controller is doing, we're looking at pretty similar numbers
between the flash cells in thumb drives and "SSD".

Only because it doesn't come with a USB connector! ;)
