  • No, but you’ll have much more overhead. I have a VM that hosts all Docker deployments which don’t need much disk space (most of them)

    This is a big point. One of the key advantages of docker is the layering and the fact that you can build up a pretty sizeable stack of isolated services based on the same set of core OS layers, which means significant disk space savings.

    Sure, 200-700MB for a stack of core layers seems small but multiply that by a lot of containers and it adds up.


  • Ultimately it’s a matter of personal choice and risk tolerance.

    The Z1 will be simpler and have larger capacity, but if you have a drive fail you’ll need to quickly get it replaced or risk having to rebuild/restore if the mirror drive follows the first one to the grave.

    Your Z2 setup right now can have two drives fail and still be online, and having a wider spread of power-on hours is usually a good thing in terms of failure probability.

    I manage a large (14,000±) number of on-site RAID1 arrays in various environments and there is definitely a trend for drives shipped at the same time to fail at roughly the same time. It’s common enough that we often intentionally swap drives out before shipping a new unit to the customer site.

    On my homelab, I’m much more tolerant of risk since I have trust in my 3-2-1 backup solution and if my NAS goes down it’s not going to substantially affect anything while I wait for a drive replacement.
