My main question is, does it make any sense to use openWRT on a consumer NAS that uses raid? I have an old seagate BlackArmor 220 NAS (https://wikidevi.com/wiki/Seagate_BlackArmor_NAS_220). I use it with stock firmware still, which is pretty bad. This is a 2 spindle disk NAS with raid 1. It has a single ethernet port and that's about it.
Here a the main things I need - Raid 1 (disks mirrored) - Network shares with a couple of users (samba) Nice to haves - Notification on any disk issues - Snmp monitoring
There appear to be Debian builds that will run on it, but I am familiar with OpenWRT. I won't need any real router functionality of course, no Wifi, no Firewall etc so seems a bit goofy. Looks like someone at least had some openwrt builds running on it Seagate BlackArmor NAS 220.
Anyway looking to see if others are running NAS-es with RAID and OpenWRT and getting valuable use out of it. Or if should just put debian on it.
