The Seagate Guardian Series brings a massive 10TB of storage space in the 3.5’’ form factor. The Guardian Series from Seagate features a total of four lines of products targeted at various marketing segments: the Barracuda Pro for gamers, the Skyhawk for surveillance systems, the FireCuda for the mobile market, and the Ironwolf for NAS. The Barracuda Pro, Ironwolf, and Skyhawk most likely shared the same internal hardware components since the specifications are pretty much identical across all three drives. They all feature 7200 RPM speeds, 7 heads and 14 disks, 256MB of cache, and support the SATA III (6 Gbps) interface. The difference between them is primarily the firmware and cache subsystem where the Barracuda Pro features multi-cache technology. Additionally, the Skyhawk and the Ironwolf probably have gone through more rigorous testing for the type of workloads they are designed for. As we can see, the Barracuda Pro is rated to operate up to 60ºC, while the Ironwolf and the Skywolf are able to operate up to 70ºC. Additionally, the Ironwolf has twice the load and unload cycle than either the Skyhawk or the Barracuda Pro.
