Question home use Windows server 2016 or 2019 storage space pool raid 5 NTFS vs Storage Spaces pool ReFS parity similar to raid-5

[LeoG7119]

Hi. I have a home server and trying to figure out which way to set it up. This is not server hardware but just a home-built PC with 3x 4tb drives running either 2016 or 2019 essentials. I used to just create a RAID-5 via disk management with NTFS but was wondering if it is better to set up a ReFS storage spaces pool with parity similar to RAID-5
My server primarily is used to back up Windows clients and some files.

Either way, RAID 5, or ReFS...what is you real backup plan?
Because neither of those are.

Those are for system availability in the face of a physical drive fail.
Not data protection.

I have an external backup as well. I was thinking that the storage spaces pool may offer something better than just an old software raid-5 in disk management. Re-sync and rebuild in raid-5 is terribly long.

Given a proper backup routine, RAID 5 or the equivalent in Storage Spaces is not needed.
And the rebuild time would be similar.

Those configs might be OK if you really needed continued uptime, in the event of a drive fail.

But if you have a real backup routine, and can suffer through the horror of an hour or so of recovery to a replacement drive, the RAID is not needed at all.

I was just thinking to take advantage of the spaces and ReFS self-recovery.

Having had RAID 1 and 5 set up in my NAS, and gone through size upgrades and data recovery....it does nothing if you do not really need that 24/7 uptime.
