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.
