sorry im new to all this as you can see, assuming i did that it would be 1) Drive one = 2tb of data 2) Mirror of 1) 3) 2tb expansion 4) 2tb expansion im failing to see what the point of mirroring drive one would be, assuming i did this would i end up with one 6TB drive in my network and not 3x2TB? i have tried reading the manual but i can't make sense of the logic. thank you again for your awnser

Drives fail. If you assume a 4 drive array, you will have about 1 disk failure per year (since consumer drives typically last 3-5 years).

With XRAID-2, you are getting single-drive redundancy. This protects your data even if one drive fails.

If two drives fail (which does happen btw) you would lose your data - so keeping up to date backups is still important. However, rebuilding the NAS from backups is a time-consuming process when you have lots of data - several days at least. So the RAID protection is still is an important benefit.

Plus, the redundancy is what makes it possible to upgrade a smaller drive with a larger one.
