The WD140EDFZ from Western Digital is a 14TB internal hard drive in the 3.5-inch size. It connects over SATA III at 6Gb/s and belongs to the 5400 RPM class, which keeps power draw, heat and noise down. Advanced Format 4K sectors are used. The drive is an OEM part, sold labelled for internal use.
Is it a fit for your recorder?
It suits light to moderate DVR or NVR use and smaller CCTV systems with a limited number of camera streams. It is not sold as a purpose-built surveillance or enterprise disk. Where capacity matters most and the recording load is modest, such as an archive copy or backup store, it makes sense. A recorder taking many busy high-resolution streams around the clock is better served by a drive designed for that duty, such as a Toshiba S300 or a Seagate SkyHawk. Our 14TB drives page lists the options.

Before you order
Look up the largest disk your recorder supports. Plenty of older DVRs and NVRs stop at a smaller size and will not recognise 14TB, so find the figure in the manual or on the datasheet first. The lower spin speed gives off less heat in a tight cabinet, which can help. Other sizes and brands sit in storage.
