2.9 eSATAII Interface Introduction
What is eSATAII?
This motherboard supports eSATAII interface, the external SATAII specification. eSATAII allows you to enjoy the SATAII function provided by the I/O of your computer, offering the high speed data transfer rate up to 3.0Gb/s, and the convenient mobility like USB. eSATAII is equipped with Hot Plug capability that enables you to exchange drives easily. For example, with eSATAII interface, you may simply plug your eSATAII hard disk to the eSATAII ports instead of opening your chassis to exchange your SATAII hard disk. Currently, on the market, the data transfer rate of USB 2.0 is up to 480Mb/s, and for IEEE 1394 is up to 400Mb/ s. However, eSATAII provides the data transfer rate up to 3000Mb/s, which is much higher than USB 2.0 and IEEE 1394, and still keeps the convenience of Hot Plug feature. Therefore, on the basis of the advantageous transfer speed and the facilitating mobile capability, in the near future, eSATAII will replace USB 2.0 and IEEE 1394 to be a trend for external interface.
NOTE:
1.If you set “SATA Operation Mode” option in BIOS setup to AHCI or RAID mode, Hot Plug function is supported with eSATAII devices. Therefore, you can insert or remove your eSATAII devices to the eSATAII ports while the system is
2.If you set “SATA Operation Mode” option in BIOS setup to
3.If you want to use the eSATAII HDD as an OS disk, please set “SATA Operation Mode” option in BIOS setup to
4.Please do not configure your eSATAII HDD as a RAID disk; otherwise, it may affect the Hot Plug function that eSATAII HDD should have.
5.Please refer to page 35 to 39 for detailed information of RAID mode,
