        cache/buffer size  = 8192 KBytes


root@deb:~# hdparm -Tt /dev/sdc

/dev/sdc:
 Timing cached reads:   14980 MB in  2.00 seconds = 7506.99 MB/sec
 Timing buffered disk reads: 212 MB in  3.01 seconds =  70.50 MB/sec

Система сейчас стоит на втором. Имеет смысл переставить на первый? Там и кэш вдвое больше, и скорость Timing buffered disk reads вдвое выше. Будет заметный прирост в скорости (в частности загрузка системы и запуск приложений)? Или особого смысла нет и можно использовать третий винт, как некий средний вариант?
