Не верю.
Там же смотрим количество записанных секторов, - Logical Sectors Written

Считаем, сколько записано в терабайтах
$ echo '67989568081*512/1000^4' | bc -l # TB
34.81065885747200000000
И это записано за 11 месяцев
$ echo '7943/24/30' | bc -l
11.03194444444444444444
Идем в документацию производителя
https://www.silicon-power.com/support/lang/big5/TBW.pdfи смотрим, что для S55 240GB, TBW = 125TB
И Logical Sectors Written, говорит, что всё не так плохо как кажется.
Под систему на sysvinit, пойдёт. В диск она стучит копейками. Сущий мизер.
