IT Pro: Seagate 8TB Enterprise Capacity 3.5 HDD v5 Review

>> See The Full Seagate 8TB Enterprise Capacity 3.5 HDD v5 Review

The Seagate 8TB Enterprise Capacity 3.5 HDD v5 offers up to 8TB of storage employing the familiar 7,200-RPM air-based design with the established PMR recording technology. Seagate's previous 8TB Archive HDD employed SMR recording technology that enables low-cost storage, but also results in a decline in performance. It's hard to beat $0.03 per GB, but for more intense environments performance becomes an important factor.

HGST is the only other vendor with an 8TB nearline-class HDD on the market, and it leverages the company's helium platform. The HGST Ultrastar He8offers lower power consumption than air drives, but also wields impressively high write performance borne of its media caching algorithms. 
Unseating the Ultrastar He8 is no small task, but the Seagate Enterprise Capacity v5 has a few tricks up its sleeve. Seagate employs a new write caching feature as well, courtesy of a NOR buffer, that is designed to deliver even greater performance than its helium-infused competition. It also features a PowerBalance function that allows it to draw less power in exchange for incrementally slower performance.

Price always factors into the equation, and pricing has traditionally been the weak point of helium HDDs. Seagate has the right boxes checked on the spec sheet, including performance, power and price, but now it's time to see if the 8TB Enterprise Capacity HDD lives up to the billing in our expansive test suite. Join us at Tom's IT Pro as we put the Seagate 8TB Enterprise Capacity v5 to the test.
