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 "PCIE-SATAII 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
power-on and in working condition.
2. If you set "PCIE-SATAII Operation Mode" option in BIOS setup to IDE mode, Hot
Plug function is not supported with eSATAII devices. If you still want to use eSATAII
function in IDE mode, please insert or remove your eSATAII devices to the eSATAII
ports only when the system is power-off.
3. Please refer to page 28 to 32 for detailed information of RAID mode, IDE mode and
AHCI mode.
