From the above, the reallocated sector count is fine, none of the disk
seem to be having surface problems.

The UDMA errors are MUCH higher for sdb, as is the power-on hours. It
is claiming about 6 years powered on, which is a bit weird alright. If
it is having to recover UDMA errors, it will be much slower to
operate.
