before we supported only disks with block size 512 B. Now, we support also
disks with 4 kB (aka 4k), for now only on Gluster SD. If you want to learn more about
this feature, you can check slides [1] and I noticed that videos recording of
Nir's talk he had on Fosdem is already available, so you can watch whole
talk [2].

yes, now Gluster SD should work without 512 block size emulation
1:30 p.m.
Is there performance improvements using larger block size?
