There is quite a difference between common USB flash drives and SSDs. SSDs
are supposed to replace a HDD while USB drives are not designed for it.
One difference is the type of wear leveling, also documented here
http://en.wikipedia.org/wiki/Wear_leveling

There are exceptions of course, for example there some "industrial grade"
devices, but the commonly used ones can not be compared.
