Capacity and interface

This Western Digital Ultrastar DC HC555 is a 14 TB 3.5-inch internal hard drive with a SATA interface. It is built for desktop and server environments that need high-capacity bulk storage. The drive uses energy-assisted magnetic recording and a 512e sector format to deliver 14 TB in a standard form factor. It spins at 7200 rpm for consistent throughput in multi-drive arrays.

Who it suits and who it does not

This drive suits system builders and IT managers who need large-capacity SATA storage for NAS, RAID or archive workloads. Buyers who require a smaller capacity or a different physical size should look elsewhere. Systems that only accept 2.5-inch drives cannot use this 3.5-inch model. Workloads that demand the low latency of solid-state media will not be satisfied by a mechanical hard drive.

Deciding specification

The 14 TB capacity is the single specification that determines whether this drive meets the storage requirement. The SATA interface and 3.5-inch form factor must match the host system's drive bays and controller. The 7200 rpm spindle speed and 512e format are fixed characteristics of this model. If the needed capacity is lower or the interface must be something other than SATA, this is not the correct part.

Is the 14 TB capacity the only option for this Ultrastar model?

The listed model 0B48721 is offered in a single 14 TB capacity.

How does the 7200 rpm speed affect everyday server workloads?

What does the SATA interface limit in a modern backplane?

The SATA link caps sustained transfer at the interface's 6 Gbit/s maximum regardless of drive capability.
