I make a random 1MB chunk, then write that all over the drive, at overlapping offsets. I've been told that really clears it. On IDE-spinning-rust disks I trusted it, not sure if I should trust these modern SSD

Why rewrite the same 1MB chunk, instead of making new random chunks?
Redundant data at least opens the possibility that the drive could deduplicate.
Cause making new random was taking too much time.
