    With RAID-1 the two disks are mirrored, so adding the second drive does not add capacity - it adds redundancy. If you hot-insert a third 4 TB drive the space will increase to 7.2 TiB, and the NAS will switch to RAID-5. You still have redundancy which protects against a single drive failure.

    If you wanted jbod (no RAID) then you should start over with another factory reset (with only one drive installed), switch to FLEXRAID/JBOD, and hot-insert the second drive.

    Adding a new disk to the RN104 is easy, I am puzzled by your comment on "not simple to add more disks".

I have been looking for some help on the same lines -

I have a ReadyNas 104 which had the default XRaid setup with 2X3TB and a 4TB HDD Disks installed. My intial setup was 2X3TB and then I hot added a 4 TB drive. It seemed to increase the space as I remember. However after a few weeks of adding the 4TB, the unit developed minor power supply issue (not related to the additional storage in any case) and I received a new RN104 unit (replacement). The device arrives in a day, I have my old HDD with me (with all data) however now I am confused on how to setup this new device so that I do not lose any of my data and this volume can be rebuild the way it was with the previous setup I was running.

Anyone who has ever tried this ? Can someone give me some steps / guidance on how to go about setting this up ?

Much appreciate if anyone can help!!

Thanks

If you mean that you have all the hard drives, then the best procedure is
(a) install a scratch disk in the new RN104, and install the same firmware you had on the old.
(b) shut down the RN104, and insert all the old hard drives (ideally in the same slots as the original, but that is not strictly necessary).
(c) turn on the RN104, and it should come back up with the original volume and settings.
