SSD have to fragment in the same way memory fragments, due to the Alloc->Delete->Realloc cycle. I.e., doesn't there have to be garbage collection?

No idea if B is actually true, but I've >read it enough times to lead me to believe that it is. I've heard/read that SSD's (even thumb drives) actually randomize the physical location of written data in order to "spread out" the writing, so a given memory cell doesn't wear out before any other.
