Hey folks. I have tried to get some basic info on how the NAS542 handles drives of different sizes and if it is possible to "grow" a RAID 5 ? I understand that adding 2 x 2TB and 2 x 1TB will be seen as 4 x 1TB for now but later on down the line, can I replace the 2 x 1TB drives to 2 x 2TB (obviously one at a time) and then end up with 4 x 2TB (6TB RAID5 total). Is that kind of thing possible with one of these ?

The design of NAS to change RAID type is only for basic and RAID 1 and RAID 1 to RAID5
Here is the information from Zyxel KB article:

If you now currently is RAID5 with 4 HDD (2x2TB, 2x1TB), then you can expand the capacity by replacing the 1TB HDD one by one, means to replace 1 x 1TB and expand capacity and sync data, after done, replace second 1TB HDD and do again expand capacity and sync data.
After all finished, the capacity size will become 6TB total RAID.0
