HGST Announces 10 Terabyte PMR Hard Drive

HGST, a division of Western Digital, has announced its second 10 terabyte helium-filled hard drive. The Ultrastar Archive Ha10 , announced back in June, was a shingled magnetic recording (SMR) drive. Now HGST has launched the Ultrastar He10, a 10 TB helium-filled HDD using traditional perpendicular magnetic recording (PMR). With a total of 7 platters, each platter stores around 1.43 TB. AnandTech reports:

Hard drives are struggling to reach the 10TB capacity point with traditional PMR technology. While Seagate did announce a few 8TB PMR drives earlier this quarter, it really looks like vendors need to move to some other technology (shingled magnetic recording or heat-assisted magnetic recording (HAMR)) in order to keep the $/TB metric competitive against the upcoming high-capacity SSDs. As of now, helium seems to be the only proven solution causing minimal performance impact and HGST appears to have a strong hold in this particular market segment.

Ars Technica has some speculation about the price:

There's no price listed for the Ultrastar He10, but it'll probably cost about £600/$800. The first helium-filled drives were extortionately expensive, but the He8 is now down to around £400/$550, which isn't bad for an enterprise drive (these things have a 5-year warranty and other such niceties, too). Seagate's shingled 8TB drive is much cheaper (£170/$200), but you get a shorter warranty and less enterprisey stuff.

    When WD bought out HGST, they had to sell off then-new 1TB Platter-based drives off to Toshiba. I wonder if this model is based on the same platter.

    BTW, cramming seven platters into a single unit means hotter operation and heavier mechanical stress. You should stress-test this thing before putting into production, and given its capacity, it will take a long time to test each.

    These actually run cooler than normal drives due to the concurrent use of helioseal/helium gas. Look at the TCO chart in the anandtech article. 8 racks, 1920 hdds use 10 kw of power vs 15.4 kw for 6 TB air filled drives and 17.3 kw for 8 TB air filled drives. Other articles show similar benefits for helium drives like operating temperature and vibrations.

    Seagate has created a six platter drive without "resorting" to helium. I am not sure about 7 platters:

    That's why they fill the case with helium - much lower friction than air, so they can pack more platters in without changing the heat/power budget.

    I would worry more about lifespan of the seal than initial stress testing, helium is notoriously difficult to keep contained.
