Western Digital Launches Ultrastar DC HS760 HDD with Dual Actuator Technology

Posted on 31 Jan 2023 📧 Subscribe

Western Digital has announced the release of its new hard drive, the Ultrastar DC HS760, which comes equipped with dual actuator technology. This new technology increases the power of the drive by almost double, making it a great choice for data centers.

The Ultrastar DC HS760 has been discovered on Western Digital’s product pages and is expected to double the sequential data throughput when compared to the Ultrastar DC HC560, which has a peak of 291 MB/s. With the dual actuator technology, the HS760 is expected to reach 582 MB/s, slightly higher than Seagate’s Exos 2X18, which has a maximum of 554 MB/s.

The Ultrastar DC HS760 is also expected to increase energy efficiency by 70% for random access and is recognized as a “dual logical unit number (LUN) SAS device” when connected via the SAS interface. It is managed as two volumes of 10 TB each, allowing for increased IOPS as with a RAID 0 from two separate HDDs.

The rest of the technology of the HS760 corresponds to that of the HC560, with 9 magnetic discs rotating at 7,200 RPM in a helium-filled 3.5-inch housing. Western Digital uses ePMR and OptiNAND to achieve 2.2 TB per platter, instead of the disadvantageous SMR technology.

Information on the price and availability of the Ultrastar DC HS760 is not currently available, but it is meant for data center use and not intended for private end-users. The HS760 is expected to have a workload rating of 760 TB per LUN per year, while the HC560 is specified at 550 TB per year.

In conclusion, the Ultrastar DC HS760 with its dual actuator technology is a great addition to Western Digital’s line of hard drives, offering increased performance and energy efficiency for data centers.

The Ultrastar DC HS760 is a cutting-edge hard drive from Western Digital that offers superior performance and capacity compared to its predecessor, the Ultrastar DC HC560. The DC HS760 leverages Western Digital’s 2.2TB/disk areal density leadership to deliver both high performance and high capacity in a data center drive. With its dual actuator design, the DC HS760 delivers up to 2x sequential throughput, up to 1.7x random performance, and up to 37% more power efficiency compared to single actuator drives.

Additionally, the DC HS760 meets modern data center reliability requirements with its 2.5M MTBF5 (projected) and 5-year limited warranty. It is optimized for heavy application workloads and can handle up to 500TB per year per LUN. The drive implements OptiNAND technology, which integrates an iNAND Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media, and features ArmorCache, which provides the best of both write cache enabled (WCE) and write cache disabled (WCD) modes for performance and data protection.

Overall, the Ultrastar DC HS760 offers a reliable and high-performing solution for demanding data center applications, surpassing the capabilities of the Ultrastar DC HC560 in terms of performance, efficiency, and data protection.

  2. I am thinking of building a small RAID of an array for video editing. Level 1 is possible, but what will happen if one part of the disk fails. In any case, I would wait for a product for raid 5 on one drive LOL

  3. i think this is great im excited too especially for gaming, i know not everything works as well on hdd, but bieng able to horde games and use primocache with ssd as cache works extremely well, ive outgrown my ssds, and dont want qlc no thank you, so ill do tlc, ssds as a cache with massive hdds, and for backups, hopefully ill be able to replace my older firecudas with mach 2s or wds dual actuators, thatd be fun. always apretiate your videos man, the hdd is not dead, its still great tech, particularily if you have tons of data you want to use.

  6. I still want my fabled 12cm ‘1petabyte single optical disc’.. I’ll even take an 8cm ‘500 TB single optical disc’ … or perhaps go back to the caddied Mini-Disc with a ‘250 TB single optical disc’ capacity, even if it’s only a write once, multi-session finalizing function? 😛

  17. Sometime back around 1988 I was taking a course in database administration. Our small class had a field trip to the local IBM office where some engineers explained how HDDs work. I said there seemed to be plenty of room inside the demo HDD for another actuator with another set of heads. Why not use it? They were incredulous. Why would I even suggest such a thing? Their HDDs will always write/read much faster than the rest of the data stream could support!

    This is the kind of ‘forward thinking’ that got IBM to where it is today.
