I've been very happy with my Synology NAS that has served me so well, but forcing this sort of vender lock-in is simply unacceptable. I suppose this means I'll have to look for some other solution.

The problem is - I've formatted my drives with SHR(Synology Hybrid RAID - essentially another exclusive lock-in) and this would mean a rather painful transition to the new drive, since this now involves getting a whole new drives to format and move data to, rather than a simple lift-and-drop.

Ugh.
