WD Gold drives are oriented toward data center use - and so feature high speeds paired with increased reliability features. For performance they use the SATA 6Gbps interconnect and spin at 7200rpm. Most of the Gold drives have 128 MB cache, but this 12TB version has 256 MB. Reliability is ensured with dual actuator head positioning, RAFF for vibration protection, and TLER to help avoid drives dropping out of arrays (RAID). Even though they are aimed at data centers and other enterprise applications, the features these drives have make them excellent options for users who need high capacity, reliability, and performance.
This 12TB model is helium filled to reduce drag and friction, as well as perpendicular magnetic recording to maximize data density on the platters.

Nick Krader (Inventory Technician) Says:
Currently is one of the biggest HDD you can purchase. These drives are fast (for a mechanical drive) and quite reliable. The best way to utilize these drives would be in a multi drive RAID array as many of the features that you pay for in these drives would only benefit if you were running more than one. These are not the quietest drives but there really is no substitute when you need a massive storage drive that has a very reasonable cost per TB.
