Я снабдил несколько серверов связкой Intel S3610, и меня немного беспокоят значения «Raw Read Error Rate». Инструменты показывают, что все диски исправны, и других ошибок нет, как показано в виде полных данных SMART, вставленных ниже для одного диска.
Эти значения что-нибудь значат?

В Raw Read Error Rate поле часто форматируется закрытым, скрытым образом или полностью используется для кодификации другой информации. Короче говоря, не обращайте внимания на исходное значение.
Лучше внимательно изучить normalized, threshold и worse данные: по ним мы видим, что ваш диск в хорошем состоянии.
Другими важными областями являются Uncorrectable Error Count, Re-allocated Sector Count и Percent Drive Life Remaining: их исходные значения обычно кодируются в абсолютных значениях, и они показывают ваши диски как здоровые.
