If you'd been reading l-k, you would have seen several threads refering to an existing tool to profile disk activity in the manner of sar!

ftp://ftp.uk.linux.org/pub/linux/sct/fs/sard-0.3.tar.gz
provides disk % busy, average queue, CPU wait times, throughput and number of IOs per second read/write for each disk and each partition. I hope to fold these into the main kernel at some point.
