I've been using gparted for creating and managing filesystems for so long I didn't really think about it too much. But now that I'm fooling around with RAID, I've bumped into soemthing I maybe should have been paying attention to all along.
It's the block size. Gparted does not seem to have an option to set the block size when it formats a new partition. It just used 512B blocks. I'm seeing recommendations for 4 KB blocks on large filesystems, and most of mine are 32GB, and I have two that are 7TB and 11TB RAID arrays respectively.
Does anybody know how much of a difference this makes? I'd be interested in what anyone has found.
