Adding 20 percent storage to its previous high-capacity models, Seagate now offers 12 TB hard drives in a 3.5-inch size. These spinning disks feature transfer rates up to 250 MB/s and use still relatively new helium gas technology usually reserved for enterprise drives to reduce friction throughout the eight-platter internals. The new 12 TB drives come in three Guardian Series flavors: Barracuda Pro for desktop use and IronWolf or IronWolf Pro for use in network-attached storage devices that often feature multiple-drive RAID configurations.
The Barracuda Pro and IronWolf Pro come with a five-year warranty and two years of Seagate Rescue (the company's data recovery service) while the more affordable IronWolf version comes with a standard three-year warranty. The $70 difference between the Pro and non-pro versions could add up for a small studio's multi-drive bay, but the extra warranty and two-year peace of mind with data recovery should something go wrong might make it worthwhile to spring for the IronWolf Pro.
The Barracuda Pro will go on sale for $529.99 while the IronWolf and IronWolf Pro will sell for $469.99 and $539.99, respectively. While that might sound expensive for a single drive, these prices actually represent fairly reasonable costs of roughly $40-45 per terabyte.
