Сыпется диск?

Здраствуйте. Недавно на сервере увидел сильное увеличение LA, бывает маленьким, но иногда бывает сильно большой, думал может какой то сайт сильно грузит сервер, разобрал логи, больше всего что проблема не в сайтах. Есть подозрение на диск, смущает параметр Raw_Read_Error_Rate - 189717247, это нормальное значение?

Посмотрите пожалуйста информацию по этому диску, может он умирает уже и пора менять

Вот смарт статус диска
