I am planning a home OMV NAS build with 3-4 hard drives in an enclosure connected to a Debian server with software RAID using ZFS. Looking at available drive enclosures, there are enclosures specified as RAID enclosures and other models as non-RAID enclosures. I assume the RAID enclosures would be both redundant and possibly incompatible with software RAID. My questions, as an obvious newbie, are:
- if the RAID enclosures are not necessary but also not incompatible, would they offer any advantage for my build?
- the non-RAID enclosure descriptions say "Single Mode" -- what does that mean?
- do drive enclosures need to provide/support multiple physical connections to the server for performance?
I'll be very grateful for advice.
