Ultrastar DC HC560 Hyperscale cloud, CSPs, enterprises, smart video surveillance partners, NAS suppliers and more, need storage solutions to meet the exponential growth in data creation. When it comes to cost-effective storage of data at scale, hard disk drives (HDDs) continue to play a central role. IDC projects that in 2025, HDDs will represent 82% of storage capacity sold to the enterprise market*. HDDs deliver the capacity, performance, and reliability needed to store vast amounts of data today and well into the future. Investments in HDD technology remain critical to supporting worldwide data growth. Western Digital has developed flash-enhanced drives with OptiNAND technology by vertically integrating the company’s leading NAND flash with its world-class HDDs. Western Digital HDDs have been leaders in areal density with industry first technologies of energy-assisted magnetic recording technology (EAMR), triple-stage actuator (TSA), HelioSeal, and now OptiNAND technology. Higher areal density means higher capacities to meet storage challenges.

Western Digital 20TB Ultrastar DC HC560 7200RPM 3.5in SAS Hard Drive (0F38652)

I know the datasheet appears to say the opposite--the Ultrastar HC560 only hits 269 MB/s transfer speeds, while the Exos X20 can reach 285. But, the HC560 has twice the cache and OptiNAND compared to the X20, which makes it significantly faster at basically any non-sequential workload.The performance of these drives also far outclasses that of any consumer drives, even WD Blacks and Seagate Barracuda Pros. The seek times have been tuned in firmware to be the fastest possible. While this means that the noise output of these datacenter drives can make them less suitable for NAS use, they are otherwise an excellent option where you want the most out of your spinning storage.I expect these drives to be extremely reliable as well.

HGST was a company known for making drives that were rock-solid in reliability, and WD purchased them in 2012. While the HGST brand was retired in 2018, the same engineers are still working to deliver products like this. Just look at how similar this drive looks to the HGST Ultrastar He12, which is now sold as the WD Ultrastar HC520.Though, some of these drives have a power disable feature that will keep the drive from turning on if it detects 3.3V power. To fix this, tape over the 3.3V pin on the SATA power connector.
