Well, there are three of us…
I’ve had/seen more issues with RAID than it solved. People who lost tons of data because the RAID controller died - disks were fine, but couldn’t read them. I finally gave in and was using RAID1 in a little NAS box - figured at least that might be ok.
One disk died. While I was getting that replaced, the other one started having issues. Glad I had backups.
