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.
- zlynx 6y agoFrom what I have seen the available spare value will decrease rapidly near end of life. As Flash cells start to fail they are replaced by spare. Because of write leveling this is delayed for a while, but then as each cell reaches its 300 or 3,000 writes, they all start to fail.
