So, I’ve got a desktop that I don’t use anymore that I’m going to try to turn into a NAS.
It’s got a core i5 and 8GB of ram (might upgrade), I believe this should be acceptable. I just bought two 7200RPM 14TB WD Drives that I’d like to put in either RAID 1, 5, 6 (Also planning to expand in the future) . And I’m planning to run OpenMediaVault on this NAS. (OMV uses linux mdadm software raid. The NAS will be primarily used for local cloud storage and in home streaming.
So here are some of my questions:
1. Desktop spec wise it should be okay right?
2. Let’s say I have Drive A and Drive B. If Drive A fails in RAID 5 and I rebuild the array and it get functioning again. If Drive B fails later, I can rebuild it again? From my understanding this is correct. Because RAID 5 only can’t be rebuilt if multiple drives fail at the same time?
3. Considering my plans to expand my storage later, if I choose say RAID 5. And later down the road want to change to RAID 6, is that possible? Is it possible with other versions of RAID?
4. OpenMediaVault seems to have support for multiple filesystems. I was thinking of doing ext4, but I also see it has support for BTRFS, XFS, and ZFS (through and addon). Do these other filesystems have pros or cons over standard ext4?
Thanks for helpful answers and ideas
Thank you all for the great info everyone. I think I’m a little in over my head for RAID at this point in time. I think I will go with a more simple approach for some data redundancy until I learn more. Maybe running 1 of my drives and weekly backups to my second drive in case the main drive fails.
