Надо хотя бы встроенный smart-тест запустить.

Я запустил тест еще раз, результаты ниже. Меня смущает, что у обоих дисков параметр "reallocated sectors count" одинаковый. Может-ли это быть связано с тем, что они стоят в _софтовом_ RAID1? Мне кажется, что не может, но вдруг. Одинаковость этих значений для двух разных HDD мне скорее кажется какой-то фичей производителя, чем реальной проблемой.

P.S. я помню, что я ищу источник проблемы с производительностью NAS'а, а не занимаюсь академическими изысканиями :) на данном этапе я пытаюсь исключить проблему с дисками.
