The total amount of memory used will be this value multiplied by the number of devices. Set this value at boot time and in [.filename]#/boot/loader.conf#. * [[zfs-advanced-tuning-min-auto-ashift]] `_vfs.zfs.min_auto_ashift_` - Lower `ashift` (sector size) used automatically at pool creation time. The value is a power of two. The default value of `9` represents `2^9 = 512`, a sector size of 512 bytes. To avoid _write amplification_ and get the best performance, set this value to the largest sector size used by a device in the pool.
