WD Red Plus is the new name for conventional magnetic recording 
(CMR)-based NAS drives in the WD Red family, including all capacities 
from 1TB to 14TB. These will be the choice for those whose applications 
require more write-intensive SMB workloads such as ZFS. WD Red Plus in 
2TB, 3TB, 4TB and 6TB capacities will be available soon.
