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. ==== SDA ==== # smartctl -a /dev/sda smartctl 6.2 2013-07-26 r3841 [armv5tel-linux-3.10.32] (local build) Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Hitachi Deskstar P7K500 Device Model: Hitachi HDP725050GLA360 Serial Number: GEA534RF0SN60A LU WWN Device Id: 5 000cca 34dcac057 Firmware Version: GM4OA52A User Capacity: 500,107,862,016 bytes [500 GB] Sector Size: 512 bytes logical/physical Rotation Rate: 7200 rpm Device is: In smartctl database [for details use: -P show] ATA Version is: ATA8-ACS T13/1699-D revision 4 SATA Version is: SATA 2.6, 3.0 Gb/s Local Time is: Mon Mar 14 13:24:04 2016 UTC SMART support is: Available - device has SMART capability.
