I did some tests with the EARS and the effect described in the article is very noticable.

Default fdisk misaligns the sdb1 data area (63)
changing it to 64 makes formats 20-30% faster
changing it to 65-71 slower again,
changing it to 72 faster again. (+8 presumably 4096/512)

Will see what happens when I put it in an array aligned
