This motherboard supports
ATA66
,
ATA100
or
ATA133
IDE devices. Following table lists the transfer rate of IDE PIO and DMA modes.
The IDE bus is 16-bit, which means every transfer is two bytes. As the hard drive industry introduces faster and higher capacity hard
drives, the current Ultra ATA/100 interface causes a data bottleneck between the drive and the host computer. To avoid this problem,
hard disk manufactures have introduced the new Ultra ATA-133 interface technology. Compared to traditional ATA/100, ATA/133 has up
to 33 percent increase in interface speed with transfer rate of 133MB/s. ATA/133 performance is ideal for new operating systems, such
as Window XP, that demand more storage space and faster data transfer rates from more responsive computing experiences.

To make good use of this new technology and enjoy its best performance, we recommend you to pair your system with a hard disk
equipped with ATA/133 technology so that your system's need for speed on this motherboard can be satisfied.
