that's really not so impressive. you're just dumping extents down on an empty filesystem and re-reading them. you're really just measuring the fact that the FS isn't particularly getting in the way of using your hardware.

Note also that rewriting drops to 108M/sec, which is pretty unimpressive.

216M/sec - rewrite is suffering from a striding mismatch there with the COW, bs is 32k while stripe is 128k. Consumer uses 1M.

I'm wondering which volume manager and fs under linux you'd expect better performance from in this configuration?
