Disk drive render from RAID config
I want to know how much space is a result of different RAID configuration. There was a link to this but I can't find it now. I am refering to the ReadyNAS 314 with 8 Terabyte drive. Thanks

I meant if I configure the ReadyNas to RAID1 and it has 4 bays with 8 Tb drive, how much disk space will I get (including metadata)

You would need to use two-RAID-1 volumes in that case (since RAID-1 only works with 2 drives),
Each volume would be 8 TB (ignoring the small OS partition overhead), or 7.27 TiB.
RAID-0/jbod: 32 TB total (4 volumes recommended)
RAID-1: 16 TB total (two volumes)
RAID-5: 24 TB total (one volume)
RAID-6: 16 TB total (one volume, dual redundancy)
RAID-10: 16 TB total (one volume, near dual-redundancy, faster than RAID-6).
