Ultrastar DC HC550 TCG Enterprise HDD

FIPS 140-2 certificate #4084 · Western Digital Corporation · data as of 2026-10-09

Ultrastar DC HC550 TCG Enterprise HDD, from Western Digital Corporation, holds FIPS 140-2 certificate #4084 at overall level 2. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its algorithm certificates, its validation history, and the list moves this tracker has observed, which NIST does not date.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement. Observed moving to historical on 2026-09-22. It was one of the last FIPS 140-2 certificates, all moved at the 140-2 sunset on 2026-09-21.
Caveat: When operated in FIPS mode, installed, initialized and configured as specified in Sections 2.1 and 7.2 of the Security Policy

Module description

Quoted from the NIST CMVP entry for this certificate.

The self-encrypting Ultrastar® DC HC550 TCG Enterprise HDD, from Western Digital, meets or exceeds the most demanding performance and security requirements. It incorporates sixth-generation HelioSeal® technology, is the first HDD to harness Energy-Assisted Magnetic Recording (EAMR) technology and provides 29% more capacity in the same form factor as a 14TB HDD. The higher capacity enables data centers to lower CapEx and the low power consumption contributes to OpEx savings. Targeted at 2.5M hours MTBF, the Ultrastar DC HC550 provides high reliability for mission critical environments.
