SSD Optimization under Ubuntu

Reduce flush frequency

Add "noatime" on /etc/fstab UUID=f0ae2c59-83d2-42e7-81c4-2e870b6b255d / ext4 noatime,errors=remount-ro 0 1

Reserve some space for Over-provision

leave at least 7% capacity size for unformatted. (14 % is better)

Enable TRIM suuport

By default, Ubunut 16.04 will support trim operation automatically, but you could perform it manually
