rawtest

rawtest is a tool to test throughput to raw devices. A raw device is an alternative interface to a block device where the linux kernel will not buffer anything. See raw(8) for more info.

To create a raw device first make an empty partition that is at least $BLOCKS large (see fdisk(8), cfdisk(8)). Then attach the raw device to that partition (see raw(8)). Finally run rawtest on it.

ALL THE DATA ON SUCH A DEVICE WILL BE DESTROYED!!!!!

So please BE CAREFUL when using rawtest and the disk partitioning tools.
