Help adding a new Hard Drive


Recommended Posts

Hey Hidroela..

 

it is because of your raid settings.. Raid 1 is a mirror of the drives, so you will get the space of the smallest of the two drives which is 1TB... since it is a mirror you will get Volume of 1TB with 1TB backup from your 3TB drive and 2TB lost space.. If I remember right you will be able to map the remaining 2TB to a 2nd volume...

 

I would suggest you make a Volume on the 3TB drive of 3TB and a second volume of 1TB on the 1TB drive..

 

It all depend on what you want to do with the volume... If you aren't sure what the different raids do and the pros and cons. I will suggest you to read up on it..

Synology have a good calculator if you want to try out different configurations.

Bare in mind the limitations of the RAID calculator. It allows configurations that will not work for you. E.G. you start with 1TB and add 3TB then add 2TB, the calc gives you the math results but if you try it for real you will have the added 2TB disk all by itself whether you use SHR or RAID
