Yeah I moved to the 2 NAS approach. I use a thincentre m910q as live system for frequent use and 1TB of SSD storage and my old NAS as Cold storage with 40TB, which is not that frequently used and only turned on to backup active data and retrieving data which I need again

Please keep your systems up to date. :)

I second that, Seagate AND refurbished is a no go.

Seagate or refurbished is already enough to hardly consider
