Поставил для эксперимента. /boot и / в рэйде, swap - без рэйда. LVM - на рэйде, отдельные /var /usr /home. Накатил ядро xen-sources. Вопрос такой: как посмотреть производительность винтов, ввода\вывода. SMART дает только состояние винтов. Но производительность, как они работают, на запись\чтение чем поглядеть?

К примеру так:
Code:
# dd if=/dev/md1 of=/dev/null bs=1024k count=100
100+0 записей считано
100+0 записей написано
 скопировано 104857600 байт (105 MB), 1,87396 c, 56,0 MB/c
# hdparm -tT /dev/md1

/dev/md1:
 Timing cached reads:   1528 MB in  2.00 seconds = 764.32 MB/sec
 Timing buffered disk reads:  132 MB in  2.26 seconds =  58.36 MB/sec
