All of the above is true, but current SSDs should have an inbuilt algorithm
(in their controller chip) to constantly relocate/remap blocks to elsewhere
on the disk to make sure all blocks receive an equal amount of wearing out.
So while I won't say I will pay for your drive if BFS breaks it, it
*should* be OK according to everything I've read on the subject.
