iostat 라는 멋진 녀석이 있다는데
ubuntu 10.04 LTS desktop edition에서는 기본 포함되어 있지 않고 systat 패키지를 설치해야만 한다.

$ idstat -d 3
이라고만 치면 3초에 한번 disk에 대해서 리포팅을 한다.

$ iostat -d -x 5 3

Blk_read/s
Indicate the amount of data read from the device expressed in a number of blocks per second. Blocks are equivalent to sectors with 2.4 kernels and newer and therefore have a size of 512 bytes. With older kernels, a block is of indeterminate size.

Blk_wrtn/s
Indicate the amount of data written to the device expressed in a number of blocks per second.

iostat -d 2
Display a continuous device report at two second intervals.
