<b>One fstab flag that cuts disk writes</b>

<b>One fstab flag that cuts disk writes</b>
By default Linux updates a file's access time on every READ. That's a write-per-read you never asked for.
— in <code>/etc/fstab</code> add <code>noatime</code> to your root mount options
— <code>mount -o remount /</code>
Now reads don't trigger metadata writes. On a read-heavy site server that's a measurable drop in disk ops and SSD wear. Costs nothing, zero downside for web boxes. The oldest trick in the book and people still skip it. Try it tonight.
