the wear levelling in the controllers is quite good these days.. a
recent(ish) test showed a 64GB Curcial M4 being able to handle over
750TiB of data written before any issues occurred[1], it was not the
most scientific test given that just over half the drive contained
static data though, which would presumably mean it could handle more if
that were not the case!
