12 TB NAS hard drive
This 3.5 inch internal hard drive delivers 12 TB of storage for small to medium business NAS systems. It operates at 5400 RPM with a 256 MB cache and uses CMR recording technology. The drive is built for continuous 24x7 operation in multi-bay enclosures.
Check SATA power and bay count
Verify that your NAS enclosure has a free 3.5 inch drive bay and a SATA data and power connection. The system must support drives up to 14 TB capacity and be rated for up to 8 bays. Confirm the workload rating matches your expected annual data transfer volume.
Fits multi-bay NAS builds
The drive installs directly into a standard 3.5 inch hot-swap tray or fixed bay using SATA cables. NASware firmware helps maintain compatibility during RAID rebuilds on ZFS and other file systems. It frees you from drive-related rebuild failures in 24x7 environments.

Questions about this item
Does the WD120EFAX 12TB drive ship with any cables, brackets or mounting hardware?
The drive is supplied as a bare 3.5" SATA unit; SATA data and power cables plus any mounting screws or trays must be purchased separately.
When should I choose the 12TB WD Red Plus over the 14TB or smaller capacities?
Pick the 12TB model when your NAS bay count and budget align with that capacity; all capacities from 1 to 14TB share the same 5400 RPM, 256 MB cache and 180 TB/yr workload rating.
What does the 180 TB/yr workload figure mean for daily use in my NAS?
It represents an annualised average of user data transferred to or from the drive, calculated as TB transferred multiplied by 8760 divided by recorded power-on hours.
