The async device file will be reuired for enabling async I/O . This feature can be useful while dealing with raw devices and Oracle.The async I/O will be not use any system buffer and is considered to be fast .

Joel,

Async, means in a nut shell "not at the same time"

Async write means, there may be a time delay between when it was initiated and when it was actually written to a target device.

Let me know if this helped or have more questions ?
Thanks
