Western Digital (WD) Gold 12TB Hard Drive Review


Built on a standard 3.5in format but with a thickness of 26.11mm, the 12TB Gold has a spindle speed of 7,200rpm and 256MB of cache.


The drive uses WD’s 4th generation HelioSeal helium technology and PMR (Perpendicular Magnetic Recording) to support eight 1.5TB platters (discs) each with an areal density of 864 Gbit/inch2 and 16 reading heads.


A quick look at the flip side of the PCB reveals a Avago 6097 drive controller and a single Nanya NT5CC128M16IP-D1 DDR3-1600 256MB cache IC.
