Dell EMC Ultrastar DC HC550 16TB Enterprise SAS Hard Drive

The Dell EMC / Western Digital Ultrastar DC HC550 16TB is a high-capacity enterprise hard drive designed for data centers, storage servers, RAID arrays, backup systems, cloud infrastructure and other applications requiring large amounts of reliable storage.

The drive shown in the product image is labeled Dell EMC Ultrastar DC HC550 and identifies the Western Digital model as WUH721816AL5200 with manufacturer part number 0F38375. It provides 16TB capacity, a 12Gb/s SAS interface, 7200 RPM spindle speed and a 3.5-inch LFF enterprise form factor.

16TB Enterprise Storage Capacity

With 16TB of raw storage capacity per drive, the Ultrastar DC HC550 allows organizations to build high-capacity storage arrays while reducing the number of physical drives required. It is ideal for backup, archival storage, file servers, large datasets, private cloud infrastructure and enterprise storage systems.

12Gb/s SAS Enterprise Interface

This specific model uses an enterprise 12Gb/s SAS interface. SAS provides dual-port enterprise connectivity and is designed for server and storage environments using compatible SAS HBAs, RAID controllers and backplanes.

7200 RPM Enterprise HDD

The drive operates at 7200 RPM, providing a balance of high storage capacity, sequential performance and power efficiency for capacity-oriented enterprise workloads.

3.5-Inch LFF Form Factor

The Ultrastar DC HC550 uses a standard 3.5-inch Large Form Factor (LFF) design and is intended for compatible 3.5-inch enterprise server and storage drive bays.

512e Sector Format

This WUH721816AL5200 / 0F38375 configuration is identified as a 512e SAS drive. Compatibility with the RAID controller, HBA, server firmware and existing RAID-array sector format should be verified before installation.

Helium-Sealed Enterprise Design

The Ultrastar DC HC550 family uses Western Digital's helium-sealed enterprise HDD technology. The helium environment enables a high-capacity multi-disk design while helping optimize power consumption and mechanical operation for large-scale storage deployments.

Designed for 24/7 Data Center Applications

The DC HC550 family is designed for enterprise and data-center storage environments where high capacity, reliability and continuous operation are important. Typical deployments include large RAID arrays, storage servers, backup infrastructure and scale-out storage systems.

Important SAS Compatibility Information

This is a SAS hard drive, not a SATA drive. It requires a compatible SAS backplane and SAS-capable RAID controller or HBA. A standard desktop SATA controller cannot operate a SAS drive.

For Dell PowerEdge deployment, verify that the server's backplane, PERC/HBA controller, firmware, drive carrier and supported sector format are compatible with this 16TB 512e SAS drive.
