Western Digital has this week introduced its new 10TB datacenter-class helium-filled WD Gold hard drive. This drive, according to WD, boasts higher performance compared to its predecessor combined with lower power consumption. The new WD Gold 10 TB will be Western Digital’s flagship HDD for data-centers and will compete against hard drives of similar capacity from Seagate and HGST.

The WD Gold 10 TB drive (WD101KRYZ) shares the hermetically-sealed 3.5” platform with the WD Gold 8 TB, which was introduced earlier this year. The new drive is based on multiple PMR (perpendicular magnetic recording) platters, features a 7200 RPM spindle speed, a double-size 256 MB DRAM cache and is based on the SATA 6 Gbps interface (right now, WD does not offer Gold HDDs with SAS interface). Just like the other WD Gold HDDs, the new 10 TB model was designed for a variety of server applications, including small to medium-scale machines, as well as rack-mount data center servers and storage enclosures. The drive is promoted as being optimized for RAID environments and supports enhanced RAFF technology that protects against vibration (by monitoring linear and rotational vibration in real time) as well as head positioning system with two actuators, which increases positional accuracy. In addition, the WD Gold 10 TB also supports time-limited error recovery technology (TLER), which prevents drive fallout caused by extended HDD error recovery processes.

The WD Gold 8 TB model released earlier this year already featured a number of performance and energy efficiency optimizations and the WD Gold 10 TB hard drive is designed to improve even further. The 10 TB drive offers a 249 MB/s sustained sequential transfer rate (up from 205 MB/s in the case of the 8 TB model). Moreover, maximum power consumption of the WD Gold 10 TB is 7.1 W (down from 7.4 W for the 8 TB model, and significantly less than 8.6 W consumed by HGST’s Ultrastar He10 around the same ballpark as the 6.8W operating power number for the HGST’s Ultrastar He10 SATA model). Western Digital does not reveal many details about how it managed to improve performance and energy efficiency, but it is logical to assume that increased areal density, an enlarged cache, and further tweaks of electronics are responsible. As for reliability, just like other WD Gold series HDDs, the new one is rated for 2.5 million hours MTBF and comes with a 550TB of writes per year rated workload, which at the rated write speed gives 100 minutes of full sequential writes per day.

Western Digital’s Gold 10 TB hard drives are currently available at select U.S. distributors, resellers and will shortly be sold in the company’s online store. The HDD costs $847.99 when bought from CDW.

    I'd really like to see some higher capacity 2.5" drives become available for laptops and SFF solutions. The 2TB cap has been in place for years now, and the only larger drives are 15mm thick 3TB SMR drives (write performance issues).

    Seagate has a 4tb 15mm drive...4tb is nice but it's still too thick.

    Rated at 1.51 TB/day only? Ouch. So building a RAID is not supported... so much for a "flagship" "enterprise" product, lol.

    All hard drives have low write per day numbers relative to their capacity. I found out why the hard way when I purchased a 6TB Seagate and immediately filled it with 6TB of stuff. It killed it after 5 hours of continuous writing...didn't even make it to 4TB.

    WITH 100%* MORE GOLD!

    *no gold was used in the making of this product.

    Actually I would be surprised if there ISNT a fair amount of gold in there. It's very common in electronics.

    Wake me up when they get that on a single platter.

    Do you want your wakeup delivered by a unicorn behind the wheel of a flying car while you're at it?
  • jabber - Saturday, August 6, 2016 - link

    Now that would be nice!

    A friend told me he has about 100 of the 4T drives deployed with 0 failures. The reason he hasn't upgraded to any of the larger drives - they are post WD.
