WUH721816ALE6L4: Read the HC550 16TB Model Before RFQ

The photographed Ultrastar DC HC550 label provides a complete 16TB SATA model and part number. Keep both strings, the sector format and the target platform together instead of requesting an unspecified HC550 or 16TB enterprise HDD.

Selected first-party images document representative OEM and manufacturer labels. Final model, part number, availability, condition, health evidence, firmware, sector format, carrier, platform compatibility, warranty, packing and quotation remain order-specific.

The table separates photographed label fields from procurement checks. It does not confirm current stock, quoted-unit condition, health, firmware, sector format, compatibility or warranty.

01

Preserve model and part number

The photographed label shows model WUH721816ALE6L4 and P/N 0F38462. Western Digital's official part-number selector identifies that pair within the 16TB HC550 SATA range. Keep both fields because a family and capacity search can surface SAS, security and sector-format variants.

  • WUH721816ALE6L4
  • P/N 0F38462
  • Ultrastar DC HC550
  • 16TB label capacity

02

Confirm interface and sector format

The official selector documents WUH721816ALE6L4 as a 512e SATA 6 Gb/s base model. Do not transfer that format to another HC550 suffix. Record the host-visible format, controller or HBA, backplane and current array members before a replacement or capacity-expansion decision.

  • 512e model context
  • SATA 6 Gb/s
  • Controller and backplane
  • Existing array members

03

Check power-disable and cabling context

HC550 suffixes can carry different interface and power-disable details. Confirm the server or enclosure wiring, backplane behavior and applicable model documentation before installation. A drive that does not power up in one enclosure should not be diagnosed from capacity or connector appearance alone.

  • Exact suffix behavior
  • Backplane power path
  • Cabling and enclosure
  • Platform service manual

04

Request unit-specific condition evidence

The label photo is an identification reference, not proof of current inventory or health. State whether the RFQ requires new, open-box, recertified or used-tested supply, then define the available SMART output, power-on data, error history, surface-test scope and sampling rule required before PI.

  • Target condition
  • SMART and power-on data
  • Error and test scope
  • Unit or sample evidence

05

Send a complete HC550 request

Include WUH721816ALE6L4 and 0F38462, quantity, target condition, server or enclosure, controller, sector format, array context, destination and requested evidence. Final availability, condition, test scope, packing and quotation are confirmed per order.

  • Model and part number
  • Quantity and condition
  • Platform and array context
  • Destination and evidence
