Western Digital introduced the world’s fastest hard drive – 20 TB and 582 MB / s

Western Digital introduced the 20TB Ultrastar DC HS760 hard drive. The new product is the first WD hard drive to use two independent head assemblies, delivering twice the sequential read/write speed and almost double the random read/write performance of a single-drive hard drive.

The 20TB Ultrastar DC HS760 model uses two heads on Western Digital’s OptiNAND platform. The hard drive includes nine 2.2TB Energy-Assisted Perpendicular Magnetic Recording (ePMR) platters, along with NAND cache for metadata storage and write cache for better performance and increased recording density.

With two independent read head drives, the Ultrastar DC HS760 delivers up to 582 MB/s sequential read and write speeds and up to 1.7x faster random read and write performance compared to single drive and head models. At the same time, the novelty is 37% more energy efficient compared to two separate HDDs.

The Ultrastar DC HS760 is equipped with a SAS connector and is defined by the system as two 10 TB logical drives. Because logical disks are independently addressable, they require some software configuration on the host side. Therefore, not all data centers will be able to use the new drive.

The capacity of the Ultrastar DC HS760 is 2TB more than the Seagate Exos 2X18 model, which also has two drives and two heads. WD’s new product is also faster – Exos 2X18 only offers 554 MB/s. However, the Seagate solution is also offered with a SATA connection, which makes it more convenient to use.

As with all Ultrastar hard drive models, the manufacturer also grants a five-year guarantee for the new Ultrastar DC HS760. The company does not specify the costs for the HDD.
