Seagate has launched three new 12 TB helium-filled hard disk drives containing eight perpendicular magnetic recording (PMR) platters:

These are not the first 12TB drives in the market, as enterprise versions from both Seagate and Western Digital have been around for some time. However, Seagate is the first vendor to bring down the prices and ship 12TB drives in the consumer market.

From a hardware viewpoint, the three drives are similar to the Seagate Enterprise Capacity v7 drives launched in March 2017. All of them features eight PMR platters with a 923 Gb/in2 areal density in a sealed enclosure filled with helium. That said, the Barracuda Pro Compute, meant for desktop use, doesn't come with rotational vibration (RV) sensors or dual-plane motor balancing hardware. The RV sensors and the dual-plane balance / AgileArray features enable reliable performance in multi-drive enclosures. The other important differentiation aspects include firmware features, warranty / workload ratings, and value-added services like the Seagate Rescue Data Recovery.

Two of the drives come with 5 year warranties.

    I thought there was a worldwide shortage of helium? I always sneer when I see helium balloons at the hardware stores but my daughter loves them.

    I guess helium was cheaper than other noble gases.

    The amount used in hard drives is negligible compared to other applications. The largest use [wikipedia.org] is as a coolant for superconducting magnets.

    1. Look at a hard drive with the case taken off and all the components showing. Think of how little empty volume there is to cram helium in.
    2. Now look at the warranty. The sealed system is designed to work for at least 5 years.
    3. Compare to the volume of a kid's party balloon that deflates after ONE DAY.

    Not such a big deal anymore, is it?

    Helium is untrapped out of the Earth as a byproduct of natural gas production, but could be vented into the atmosphere and lost right at that point without an economic incentive. The U.S. government has bought helium to stick into the Strategic Helium Reserve.
