Proactive storage management with WDDA

Western Digital® Device Analytics™ (WDDA) provides a wealth of storage device
parametric operational and diagnostic data compatible systems; algorithms interpret
the data and direct the system to alert system administrators of specific recommended
actions to address potential issues. WDDA is intended to empower OEMs, system
integrators, and IT professionals to better monitor and proactively manage supported
storage devices to maintain optimal operation.


¹ Projected values. When final, MTBF and AFR specifications will be based on a sample population and are estimated
by statistical measurements and acceleration algorithms under typical operating conditions, workload of 220TB/
year and drive temperature of 40°C. Derating of MTBF and AFR will occur above these parameters, up to 550TB
writes per year and 65°C drive temperature. MTBF and AFR ratings do not predict an individual drive’s reliability and
do not constitute a warranty.
² Not all products may be available in all regions of the world.
³ As used for storage capacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes. Total
accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) =
1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second,
and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated
according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification
sheet. Visit www.sata-io.org for details
⁴ This drive is in compliance with the European Union Directive 2011/65/EU and Directive (EU) 2015/863 on the
restriction of the use of certain hazardous substances in electrical and electronic equipment..
⁵ Controlled unload at ambient condition
⁶ Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is
annualized (TB transferred x (8760 / recorded power-on hours)). Workload Rate will vary depending on your
hardware and software components and configurations.
