Sequential charwise output: 8.7MB/s Respectable
Sequential blockwise output: 9.3MB/s Awful, (1)
Sequential blockwise rewrite: 5.7MB/s Not great. (1)
Sequential charwise input: 9.4MB/s Respectable
Sequential blockwise output: 57.4MB/s Nice! :-)
Random Seeks: 785.9/s Wow! You sure the test was big enough...?
(1) To be expected with raid5 without writeback. This is raid5, I take it?
