Economical. Reliable. Enterprise-Ready.
The HC330 targets Tier 2 data centre applications where access speed, total cost of acquisition and proven reliability matter most.
Lower Total Cost of Acquisition
Air-filled platform keeps acquisition costs lower than helium drives while delivering enterprise-class access density (IOPs/TB).
2nd Gen Dual-Stage Actuator
Enhanced head-positioning accuracy for better drive performance reducing read/write errors at high track pitch densities.
Flash Non-Volatile Cache
NVC on both SATA and SAS models improves write performance by providing a fast staging area for incoming writes.
550 TB/Year Workload Rating
Designed for Tier 2 data centres handles demanding enterprise workloads including block, file and distributed storage.
Secure Erase & SED Options
Secure Erase (SE) wipes all data before drive disposal. SED with TCG Enterprise SSC adds full hardware encryption at rest.
2M Hour MTBF Reliability
0.44% AFR and 2 million hour MTBF backed by a 5-year Western Digital warranty for peace of mind.
CMR Technology
Conventional Magnetic Recording ensures full compatibility with all RAID levels and enterprise storage applications.
Wide Application Support
Storage arrays, rack-mounted enclosures, distributed computing, block storage and file storage architectures.
Legacy System Compatible
Standard SATA 6Gb/s and SAS 12Gb/s interfaces with 512e format drop-in compatible with existing infrastructure.
