The Western Digital Ultrastar DC HC650 is a 20TB capacity enterprise-class hard disk drive utilizing shingled magnetic recording (SMR) technology, purpose-built for sequential write-heavy cold-archive and deep-storage applications at hyperscale data centers. The drive delivers exceptional capacity density and compelling $/TB economics, making it particularly suited for write-once, read-rarely workload patterns where sequential access dominates.
Designed specifically for cloud provider bulk deployment in archive tiers, the HC650 20TB leverages SMR's higher track density to maximize storage capacity while maintaining the mechanical reliability and thermal characteristics required for continuous datacenter operation. The architecture accepts the inherent sequencing characteristics of SMR technology as a design tradeoff for capacity-per-unit economics.
