    hello

    WHM 11.23.2 cPanel 11.23.3-R25971
    CENTOS Enterprise 5.2
    Linux 2.6.18-92.1.6.el5

    hdparm -tT /dev/hda
    /dev/hda:
    Timing cached reads: 11160 MB in 2.00 seconds = 5587.28 MB/sec
    Timing buffered disk reads: 10 MB in 3.10 seconds = 3.22 MB/sec

    lspci |grep -i sata
    00:1f.2 IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA IDE Controller (rev 02)
    00:1f.5 IDE interface: Intel Corporation 82801H (ICH8 Family) 2 port SATA IDE Controller (rev 02)

    disk is /dev/hda and not is /dev/sda ?
    disk is very slow, why?
