12TB, 3.5", SATA 6 Gb/s, 7200 rpm
Ultrastar DC HC500 Series
High Capacity for Massive Data and Lower Total Cost of Ownership
Driving Up Capacity and Driving Down TCO for Cloud and Hyperscale Data Centers
The breadth and depth of Big Data is driving the universal need for higher capacities across a broad spectrum of applications and workloads. Laying the foundation for a worry-free data center, Western Digital delivers the capacity to conquer the data explosion with the Ultrastar DC HC500 series of hard drives. Built using HelioSeal technology, the industry’s only fifth-generation helium platform, the DC HC500 series is designed for public and private cloud environments, where storage density, Watts/TB and $/TB are critical for creating the most cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, greater reliability ratings and extreme power efficiency. The result is a lower Total Cost of Ownership (TCO) for our cloud and enterprise customers.
Beyond Air. Helium Takes You Higher.
Responding to the complex needs of the modern data center, Western Digital has developed HelioSeal technology, a foundational building block for high-capacity hard disk drives (HDDs). This innovative technology hermetically seals the HDD and replaces the air inside with helium, which is one-seventh the density of air. The less dense atmosphere resets the boundaries and challenges of conventional high-capacity HDDs, allowing for dramatic increases in efficiency, reliability and value.

Have you ever thought of trading in your old smartphone?
Recycling your phone is a great way to help the environment and earn some extra money, and Clove Technology offers a recycling programme that pays you for your old phone(s)!
So if you're about to buy a new phone from us, or you've recently bought one, why not sell us the handset you no longer need?
How much will you offer for my phone?
That depends on its age and condition. More recent phones generally have a higher value than old ones, but other factors can affect value. These include if the phone is working or not and its network lock status. Fully working phones with an unlocked network status will command a higher value if they are in good condition.
We pledge to beat the major recycling services operating in the UK on the price they offer for your
How do I get my phone(s) back to you?
On our recycling site SEARCH, for your phone and provide details of its status and condition. We will then offer you a price for your phone. If you choose the option to Sell Now, a recycling pack to you for returning your phone.
Alternatively, you can call our recycling team on 0330 1180686, choosing option 2.
