"With this option enabled, atime data is written to the disk only if the file has been modified since the atime data was last updated (mtime), or if the file was last accessed more than a certain length of time ago (by default, one day)." Unless you want to do auditing of read-access, atime is just not relevant. Incremental backups work on mtime not atime. So I use noatime rather than relatime on my SSD laptops, just as we do on database partitions of servers since obviously there we fully expect there to be lots of reads and tracking that info is nonsense.
