Does CentOS support NCQ on SATA drives? If so is there something I must do to turn this support on?
NCQ was planned for kernel 2.6.18, but I haven't checked if it actually made it there. CentOS 5 should have at least that version of kernel (RHEL5 beta 2 uses 2.6.18). There's always probability that RH will backport it to 2.6.9.
kernel 2.6.18 supports NCQ if the driver is e.g. ahci or sata_sil24 (i.e. not sata_nv, ata_piix, sata_sil). See http://linux-ata.org/ and http://linuxmafia.com/faq/Hardware/sata.html
