14TB enterprise SAS drive

The Western Digital Ultrastar DC HC530 is a 14TB 3.5-inch internal hard drive built for data-centre workloads. It spins at 7200 RPM and connects through a SAS 12Gb/s interface with a 512MB cache. The helium-sealed design uses conventional magnetic recording to deliver sustained capacity. New condition.

Suited for high-capacity storage arrays

This drive fits servers and storage appliances that require large-scale, sequential throughput on a 12Gb/s SAS fabric. It is not for systems that lack SAS controllers, builds needing low-latency flash response, or desktop platforms limited to consumer drive bays. Workloads demanding ultra-high IOPS should evaluate solid-state alternatives.

SAS 12Gb/s interface decides compatibility

The single specification that determines fit is the SAS 12Gb/s interface; the host must provide a compatible SAS backplane or HBA running at that speed. Without SAS infrastructure the drive cannot be used, regardless of capacity or cache size. Verify controller and cabling support before purchase.

Questions about this item

What is the sustained transfer ceiling of the SAS 12Gb/s 7200 RPM 14TB drive?

The SAS 12Gb/s interface sets a 12 Gbit/s bus ceiling, while the 7200 RPM CMR platters and 512MB cache determine real-world sustained throughput.

How much noise and heat does the helium-sealed 3.5" 14TB drive generate under continuous load?

The helium-sealed 3.5-inch design reduces turbulence and operating temperature compared with air-filled drives of the same capacity.

Which host controller or backplane is required for the SAS 12Gb/s 14TB drive to operate?

A 12 Gbit/s SAS HBA, RAID controller or backplane with a compatible SAS connector and adequate 12 V / 5 V power is needed.
