Aligment to a 4k blocksize. This is what most of the SSDs and advanced
format HDDs use. Both your partitions have to be aligned to 4k block
boundaries and the filesystem you create on top of them must support
the 4k blocksize.

If you do a straight "dd" from a 512/512 disk with a filesystem using
512 bytes blocksize on top, you'll encounter a performance
degradation.
