14TB NAS drive for multi-bay arrays

The WD Red Plus WD140EFGX is a 14TB 3.5-inch hard drive built for small- to medium-business NAS enclosures. It uses conventional magnetic recording and spins at 7200 RPM with a 512MB cache to sustain heavy multi-user workloads. The drive is rated for up to 180 TB per year and supports systems with up to eight bays.

SATA 6.0Gb/s interface fits standard NAS bays

The drive connects through a SATA 6.0Gb/s port and conforms to the 3.5-inch form factor measuring 147.00mm long, 101.60mm wide and 26.10mm high. It requires a NAS chassis with an available 3.5-inch bay and a SATA data plus power cable. NASware 3.0 firmware handles RAID array rebuilding and improves compatibility with common NAS operating systems.

24x7 operation with managed thermals and power

Designed for continuous 24x7 environments, the drive balances heat output and acoustic profile for rack-mounted or desktop NAS units. Power draw scales with the 7200 RPM spindle speed during sustained reads, writes and RAID reconstruction. The 3-year limited warranty covers operation within the specified workload and temperature limits.

Questions about this item

How many terabytes per year can the WD140EFGX sustain in a 24×7 NAS workload?

The drive is rated for up to 180 TB/yr workload rate, which is the limit you will hit first under sustained write-heavy use in a multi-bay NAS.

What noise and heat levels should I expect from the WD140EFGX running continuously in an 8-bay enclosure?

At 7200 RPM the WD140EFGX produces typical 3.5-inch drive acoustics and heat; adequate case airflow is needed to keep temperatures within spec during all-day operation.

Which host interface and firmware does the WD140EFGX require to work in my NAS?

It needs a SATA 6.0Gb/s port and benefits from NASware 3.0 firmware for compatibility with up to 8-bay NAS systems.
