AHCI : put your SATA speed on the next level

hasil oprek-mengoprek membandingkan performance 2 low-end PC dengan menggunakan 2 versi OS yang berbeda (centOS 4.7 dan centos 5.3) cukup membuat saya terheran-heran. untuk spesifikasi yang sama, response sistem jadi sangat jauh berbeda.

Awalnya saya pikir apakah beda kernel-nya saja, tentu saja itu jadi alasan yang terakhir bagi saya karena sama-sama kernel 2.6.x. usut-punya usut saya mengaktifkan option AHCI di BIOS motherboard.

Advanced Host Controller Interface, which is a hardware mechanism that allows software to communicate with Serial ATA devices.

AHCI is a PCI class device that acts as a data movement engine between system memory and Serial ATA devices.

AHCI encompasses a PCI device.
