Sind umgerechnet rund 8,4 TB written in rund 5 1/2 Jahren bzw. knapp 81 Tagen Betriebszeit. Erscheint mir im Vergleich zu meinem deutlich intensiver genutzen ThinkPad X301 (rund 7,8 TB written in rund 612 Tagen Betriebszeit) auch recht üppig.

Die "Data Unit Read/Written"-Einträge erscheinen mir beim M1 auch unlogisch: Ergibt weder mit 512 Byte (== knapp 1 GB/576 MB) noch mit 4 kByte (== 8,3/4,5 GB) Sinn - und die 1,11 TB/604 GB ergäben umgerechnet 512-kB-Units (was mir wieder zu viel erscheint). Auch der Wert für die "Power On Hours" erscheint mir sehr unrealistisch - den Rechner hab' ich definitiv länger als 13 Stunden angehabt und auch genutzt. Aber ist sicher auch eine Frage, wie das Power-Management der SSD arbeitet.
