Seagate recently announced new 12TB 3.5-inch hard drives for desktop and NAS use aimed that those that need massive amounts of storage space. Those that have large data storage needs know that hard drives are still relevant due to their reliability and low price points. The new Seagate 12TB drives that were released this month make up the BarraCuda Pro, IronWolf, and IronWolf Pro product families. Today, we'll be taking a closer look at the Seagate BarraCuda Pro 12TB drive that is a successor to last years 10TB drive that we were impressed by when we reviewed it. The new model packs 2TB of additional storage capacity in the same enclosure. Seagate didn't change technologies to make a 12TB disk, so they are still using Perpendicular Magnetic Recording (PMR) in a helium filled enclosure for the 7200 RPM disks to have less drag. They managed to hit this new capacity milestone by switching to eight 1.5 TB platters rather than seven 1.43 TB platters. The reliability on the new 12TB 3.5-inch SATA III 6Gbps hard drive remains close to the same as well, so Seagate kept the five-year warranty on this model.
