M1 Mac owners are experiencing high SSD writes over short periods of time
The first line of the smartctl output everyone&#x27;s bandying about says that a total of 1% of the drive&#x27;s capacity has been used, which means that in about 16.5 years (2 months * 99 &#x2F; 12) their drive will go readonly.<p>What, exactly, is the problem with that?<p>It seems like there are a lot of assumptions in play in this &quot;headline news&quot;:<p>(1) assuming that the reported numbers are valid for this measurement at all<p>(2) that they are not a bug in the IOKit implementation used by smartctl<p>(3) that they are not not a bug in smartctl itself<p>(4) that they are directly comparable to non-M1 hardware without further processing<p>(5) that they do not increment when Time Machine or other filesystem snapshots occur<p>(6) that they do not increment when APFS copy-on-writes occur<p>(7) that they do not include the total byte size of sparsely-modified files<p>I don&#x27;t see anyone checking these assumptions yet, but if y&#x27;all do, supporting links on those points would improve this HN post considerably. There are other assumptions that could be tested too! Outrage is cool, but science is productive.
