and 4K (4096-byte) physical sectors; 512n: Native 512-byte logical
and physical sectors
*** RoHS COMPLIANT: Western Digital hard drive products
manufactured and sold worldwide after June 8, 2011, meet or exceed
Restriction of Hazardous Substances (RoHS) compliance requirements
as mandated by the RoHS Directive 2011/65/EU.
‡ DATA TRANSFER RATE: MB/s is 1,000,000 bytes
‡‡ CACHE BUFFER: Portion of buffer capacity used for drive
firmware
‡‡‡ MTBF and AFR: Specifications are based on a sample population
and are estimated by statistical measurements and acceleration
algorithms under typical operating conditions for this drive model.
MTBF and AFR ratings do not predict an individual drive’s
reliability and do not constitute a warranty.
§ OPERATIONAL POWER: 8K Queue Depth = 1 @ 40 IOPS
§§ IDLE POWER: Based on use of Idle_A
§§§ Some models of Ultrastar are identical in form, fit and
function to the respective WD Gold™ model. The only differences are
limited to the brand, label and ID string as reported by the
firmware. For these drives, any previously completed qualification
of the equivalent Ultrastar™ models should not require a
re-qualification."
