Per NetBSD's

noatime Never update the access time field for files. This
option is useful for optimizing read performance on
file systems that are used as news spools.
Given that CF cards of old only allowed a fixed number of writes before wearing out, setting
noatime on partitions not only reduced the amount of disk writes required for normal operation, but consequently extended the life of the CF card itself. As
phoenix points out, better wear-leveling algorithms has contributed significantly to extending CF life, but I still set
noatime as prudent insurance even though it is not as important a factor as before.
