I am thinking of extending my storage and I don’t know if I should buy a JBOD (my current solution) or a RAID capable enclosure.
My “server” is just a small intel nuc with an 8th gen i3. I am happy with the performance, but that might be impacted by a bigger software RAID setup. My current storage setup is a 4-bay JBOD with 4TB drives in RAID 5. And I am thinking of going to 6 x 8TB drives with RAID 6 which will probably be more work for my little CPU
Software, software, software! ZFS, mdraid, etc. USB is fine even with hubs, so long as your hubs and USB controllers (USB-to-SATA) are decent and not overheating.
