Use Case
The CD8-R is the read-intensive half of the KIOXIA CD8 family: 1 DWPD over five years. It is usually deployed as the capacity tier behind a smaller write-intensive device, which is why the 15.36TB point is the volume sku — fewer drives per node, fewer failure domains, and lower power per TB.
