Western Digital's Ultrastar HC330 (WUS721010ALE6L4) is a helium-filled 10TB enterprise HDD engineered for cost-effective bulk storage in SATA-based infrastructure. Built on CMR technology with a sealed helium enclosure, it delivers sustained sequential read speeds up to 260 MB/s while maintaining the 3.5" form factor standard across hyperscale data centers, NAS arrays, and cold-storage tiers. The 7,200 RPM spindle speed and 256 MB cache balance throughput with power efficiency—critical when deploying hundreds of drives across distributed clusters.
This SATA 6Gb/s drive targets environments where controller compatibility and TCO matter more than dual-port redundancy. Media and entertainment firms archiving video assets, cloud operators backing up object storage, and enterprises consolidating aging SAN infrastructure commonly standardize on the HC330 to avoid vendor lock-in and minimize per-TB acquisition cost. With 2 million TBW endurance rating and native Self-Encrypting Drive (SED) capability, it satisfies compliance requirements without software overhead.
