It is always wise to build in a spare however, that being said about all

have 3 disks at minimum, and then a 4th as a spare.
/me wonders in the days of reliable RAID-6 why we use RAID-5 + spare?
Me too. ;) So, with holidays ahead, two questions (as I might tackle
that soon and have not found it mentioned):
- How would one "switch" from the latter to the former? Is there
something like "grow_to_RAID_6"?
- Does RAID6 have disadvantages wrt write speed?
TIA for any comments,
greets, tobi... :)
