Tzn jest tak że są dwa dyski na drugiej szelce (slave) hdc i hdd

# hdparm -iv /dev/hdc

# hdparm -tT /dev/hdc

W innym serwerze mam podobny dysk (inna płyta) żadnych ustawień w
hdparm i :

# hdparm -iv /dev/hda

/dev/hda:
 multcount    =  0 (off)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)

 Timing buffered disk reads:  64 MB in  2.94 seconds = 21.77 MB/sec


 Jeżeli ktoś ma jakiś pomysł to piszcie śmiało, bo to trochę dziwne że
 ten drugi jest 10x szybszy.
