Hi @dolbyman thanks for the response. I suspected this might be the case… I guess I have some work to do over the coming weeks then. I’m relatively unfamiliar with RAID setups so bear with me. Does this mean in the NAS I use 2 x matching SSDs for the RAID 1 (on one volume), install OS and apps on this volume, and then set up the TR004 on its own volume as RAID 1 also (so use two/four matching SATA HDD) for the data storage?
If so, in the TR004, if I start with 2 HDD can I add a further 2 HDD later on in the same volume/pool as and when I need more storage?
