14 TB SAS enterprise drive
The Western Digital Ultrastar DC HC530 provides 14 TB of storage in a 3.5-inch form factor with a 12 Gb/s SAS interface. It is built for cloud, hyperscale and high-density data-centre workloads where capacity and reliability are primary requirements. The helium-sealed design and CMR recording suit massive scale-out deployments and bulk object storage. It fits NAS appliances such as Synology and QNAP as well as enterprise backup targets.
Sustained write performance
HelioSeal helium sealing reduces internal drag so the 7,200 RPM platters maintain consistent throughput during long sequential writes. The 512 MB cache absorbs burst I/O while dual-stage microactuator and TDMR keep heads on track under rotational vibration. Rated 25,000,000 hours MTBF reflects the design goal for continuous operation in multi-drive enclosures. Workloads such as Hadoop analytics or Ceph object stores benefit from steady rather than peak-only speeds.
Helium-sealed 3.5-inch build
The hermetically sealed helium chassis lowers power draw per terabyte and eliminates the need for a breather filter, simplifying rack-density planning. Standard 3.5-inch mounting holes and SAS connectors allow drop-in replacement in existing drive bays and backplanes. No special cabling or adapter brackets are required beyond a 12 Gb/s SAS host bus adapter. The drive targets integrators who need maximum capacity per slot without changing chassis infrastructure.

Questions about this item
How much heat and power will the 14 TB helium-sealed drive generate when running continuously in a server?
The HelioSeal design delivers outstanding power efficiency measured in Watts per TB, so a 14 TB unit at 7,200 RPM produces less heat per terabyte than conventional air-filled drives during all-day operation.
What host interface and controller does the 12 Gb/s SAS drive require to function?
The drive needs a 12 Gb/s SAS host bus adapter or RAID controller with a compatible SAS connector; it will not operate from a standard desktop motherboard without that controller.
Can the 3.5-inch 512e SAS drive share a backplane with older 6 Gb/s SAS enterprise drives?
Yes, the 12 Gb/s SAS interface is backward compatible with 6 Gb/s SAS backplanes, allowing the WUH721414AL5204 to run alongside earlier enterprise drives in the same enclosure.
