Enterprise capacity drive

The Western Digital Ultrastar DC HC550 provides 16TB of storage in a 3.5" form factor. It operates at 7200RPM and connects through a SAS 12Gb/s interface. The drive carries a projected 2.5M hour MTBF rating for continuous operation.

Controller dependent integration

The SAS interface requires a compatible disk controller or host bus adapter in the server or storage array. Standard desktop motherboards lack the necessary SAS connectors and protocol support. Installation consumes a single 3.5" drive bay and a SAS data cable plus power.

Suited for bulk storage tiers

This drive suits administrators expanding capacity in RAID arrays, backup appliances or near-line archives where sequential throughput matters. Buyers needing boot drives for workstations or low-latency transactional workloads should evaluate solid-state alternatives instead.

Perguntas sobre este artigo

What sustained workload limit appears first on the 16TB 7200RPM SAS drive?

The 2.5M hour projected MTBF rating indicates the reliability target that defines the drive's sustained workload limit.

How much heat and power does the 3.5" 16TB SAS drive produce when running continuously?

The SAS 12Gb/s interface and 7200RPM spindle determine the thermal and power profile during all-day operation.

Which disk controller must I already own for the WUH721816AL5204 to work?

A SAS 12Gb/s capable disk controller is required for the drive to function in a server or array.
