RN314 Vertical expand of 4x2TB disks calculating total capacity
Hi community, i do have a netgear 314 running on latest firmware and 4 x 2 TB hard disks in tradition raid (one logical drive) I am planning to replace two of the hard disks with 4 TB drives eac...
2x4TB+2x2TB will give you 8 TB of volume space with xraid.
The rule is to take away the largest disk and sum the rest. That is 4TB + 2 TB + 2 TB = 8 TB.
Technically this uses two raid layers- 4x2TB RAID-5 and 2x2TB RAID-1 for the vertical expansion. These are mounted as a single volume, but you can see the layers if you look at the disk partitioning with ssh,
With standard RAID-5, there is no layering like this. So only 2 TB of the two 4 TB drives can be used, which would give you 6 TB volume space.
