We can get each drive's serial number, power on hours, and manufacture date with the following one-liner:

for dev in {a..e}; \
  do echo "### /dev/sd$dev" && \
  sudo smartctl -a /dev/sd$dev
done

Make sure to update this list only when a disk is newly installed. Also note the date of installation for the disk.

Or, if you're only updating one drive:

1. Set the $dev variable to the drive letter you want to check (e.g. for /dev/sdr, use dev=r)
2. Run the one-liner: smartctl -a /dev/sd$dev'
