The 20TB Red Pro comes from Western Digital’s NAS line of hard drives, utilising its unique OptiNAND technology. This marries mechanical and flash storage technologies to achieve higher capacity with a form of conventional magnetic recording (CMR) that’s much faster than competing shingled magnetic recording (SMR) drives.
