> "most SSDs only last for about 100-200TB of write"

My 3.5-year old MacBook Pro has 119 TB of writes, and still claims 79% "available spare":

  Available Spare:                    79%
  Available Spare Threshold:          2%
  Percentage Used:                    15%
  Data Units Read:                    256,111,725 [131 TB]
  Data Units Written:                 232,470,299 [119 TB]
  Host Read Commands:                 2,872,362,421
  Host Write Commands:                1,547,764,735

That said, my 1-month old M1 MacBook Air is already up to 7 TB writes, so seems to be writing at a significantly higher rate. Both are 8GB machines.
