With many new hard drive disks the physical sector size is 4096. Would it be possible to make the system use a logical sector size of the same size, rather than the default logical sector size of 512?
How would you configure that?
There is a difference between block size and cluster-size but there is no such thing as logical sector size in ext4.
Probably you already have an IO block
of 4096: try doing a stat .bash_logout
in your home directory.
File: ‘.bash_logout’
Size: 220 Blocks: 8 IO Block: 4096 regular file
For more info: man mkfs.ext4
And finally: Stop worrying! ext4 uses heuristics to format your drive as efficiently as possible. ;-)
