Not enough so to notice. SSDs are direct access; no address takes any
longer to access than any other. There is no seek time, only a fixed
access time. Accessing two blocks at opposite ends of the address space
takes no longer than accessing two almost-adjacent blocks. (Accessing
two *adjacent* blocks is, of course, fractionally faster because you
just do it in a single streaming read, but in practical terms you'll
never notice the difference.)
