HTG Explains: Why Linux Doesn’t Need Defragmenting

An interesting note to me is the remark concerning defragmenting SSD. Specifically, SSD defrag is unnecessary (because of direct addressing), but more significantly, SSD defrag cuts SSD life! If Linux builds-in defrag, then perhaps life becomes an ascendant issue? Would really like to run across some serious data concerning MTBF between SSD and mechanical hard drives. What I've read so far suggests SSD life is less !

True? Or not?

PS. At least I now realize I should never defrag an SSD drive. At best, next to no benefit.
