Noa Himesaka (姫 坂 乃 愛, Himesaka Noa) is one of the very cute and funny main characters from the anime series Watashi ni Tenshi ga Maiorita!. She noas a lot about techloligy.

Noa frequently advises the linux users of /g/ to add the noatime mount option to their /etc/fstab in order to improve disk performance and increase the lifecycle of SSDs. By default, linux filesystems keep track of the most recent time that every file was last accessed. Updating this "atime" attribute in the filesystem data increases the number of reads and writes to the disk, which slows read/write performance and also uses up read/write cycles in SSDs. The noatime option stops the operating system and from keeping track of this atime attribute for files. The equivalent mount option for directories is nodiratime.

An example of an /etc/fstab entry that uses these option looks like:

UUID=00000000-0000-0000-0000-000000000000 / ext4 defaults,noatime,nodiratime 1 1
