Product Overview

Reimagining the HDD to Meet the Growth of Data

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. 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 our leading NAND flash with our 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.


20TB HDDs with OptiNAND Technology

OptiNAND integrates an iNAND® Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media, and incorporates innovative changes to the firmware algorithm and system-on-a-chip (SoC). OptiNAND is not a hybrid technology. The drive works smarter, with enhanced firmware algorithms taking advantage of expanded metadata that has been offloaded to the iNAND, enabling more tracks per inch (TPI) with resulting increased areal density.

Features


• 20TB capacity in a standard 3.5-inch form factor.
• ePMR & CMR technology works with all capacity enterprise applications & environments.
• OptiNAND for highest capacities.
• Reliable, field-proven, 7th generation HelioSeal design delivers outstanding power efficiency.
• Industry-leading HDD technologies; OptiNAND, EAMR, TSA, HelioSeal.
• 2.5M hours (projected) MTBF rating & 5-year limited warranty.
• Self-Encrypting Drive (SED) options.

Applications
• Cloud and hyperscale storage.
• Massive scale-out (MSO), high-density data centers.
• Distributed file systems.
• Bulk storage using object storage solutions like Ceph™ and OpenStack® Swift.
• Primary and secondary storage for Apache Hadoop® for big data analytics.
