How to upgrade NAS540 and what options

Victor Posts: 8  Freshman Member
When I originally set up my NAS I used 4X1TB disks on a RAID5. I have now run out of space so I need to upgrade. What is the process to follow so I do not lose all the info currently in the disks? Do I have to do an external backup or something?  Since I will upgrade I need to buy disks. What is the best option for this model?

    For external backup I bought cheap(ish) 6TB USB3 disk that is stored in basement.

    Yes, replacing disks one by one can be done without losing data.
    But again, we aware, the process isn't fast.

    External backup is always to recommend!
    When backup done, You can replace disks one by one and let the RAID-set rebuild before replacing next disk.
    Did that a while back (from 2TB to 4TB disks) and yes, rebuild may take some time so be really patient!

     I bought 4 x WD Red NAS Hard Drive WD40EFAX
     Got great price, and these has decent performance for the buck.

    Thanks Jocke, I struggle with external backup that is not cloud because if something happens to my NAS (fire, flood, etc), it would affect the external backup too. I need to look into cloud storage options.

    So when rebuilding, removing one drive does not remove specific data attached to it? I am not too familiar with RAID so my question make not make sense.
