Well, theoretically you will have more track-to-track seeks, as some
blocks will span cylinders, but I doubt that will have measurable
impact on lifetime, compared with the gains you could harvest if you
spin it down for even just 1 hour a day...

Read-Only/Read-Write makes no difference that I know of for hard-disks.

Again: I doubt it will be measurable.

Never attribute to malice what can adequately be explained by incompetence.
