I added this in the wiki performance section.
I think it would have been informative if also a test with one drive in a non-raid setup was described.
Since the performance of bonnie++ deals with single threads/a raid1 would probably closely match it but yeah I could do that sometime.
Are there any particular findings you want to highlight?
Not in particular, just I could never find this information provided anywhere that showed all of the raid variation/types in one location that was easy to read.
Is there some way to estimate random read and writes from this test?
The sequential input and output and re-write speeds are the most important.
Are the XFS file systems completely new when running the tests?
Yes, after the creation of each array, mkfs.xfs -f /dev/md3 was run to ensure a clean mount and cron was also off throughout all testing.
Best regards keld
