Well, I tried 3 scenarios with the stride/stripe-width settings:
(1) None, mkfs.ext4 with defaults.
(2) Using the -E option to set the stride/stripe-width to match the disk array
configuration.
(3) Using LVM with defaults.
There was no difference in writing to the disk.

I'm wondering if anyone has tried using stride and stripe-width options when
creating an ext4 filesystem on a hardware RAID5 array.
Does it improve the performance of the array?
Should you create the filesystem directly on the partition? What happens if
you create it on a logical volume that is created on the physical partition?
The LVM volume was created without options, ie, defaults. I know LVM supports
stride and stripes as well but I dont know how they map to a physical RAID
device so I've never bothered with it.
