Ultrastar DC HC500 Series

  • High Capacity for Massive Data and Lower Total Cost of Ownership
  • Solves TCO Challenges
  • High Capacity – Up to 18TB HDDs, drop-in ready for Big Data workloads
  • Low Power – Up to 58% lower idle W/TB than 8TB Ultrastar air-filled drives
  • More Reliable – 25% higher MTBF rating than air-filled HDDs



Driving Up Capacity and Driving Down TCO for Cloud and Hyperscale Data Centers

The breadth and depth of Big Data is driving the universal need for higher capacities across a broad spectrum of applications and workloads. Laying the foundation for a worry-free data center, Western Digital delivers the capacity to conquer the data explosion with the Ultrastar DC HC500 series of hard drives. Built using HelioSeal technology, the industry’s only fifth-generation helium platform, the DC HC500 series is designed for public and private cloud environments, where storage density, Watts/TB and $/TB are critical for creating the most cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, greater reliability ratings and extreme power efficiency. The result is a lower Total Cost of Ownership (TCO) for our cloud and enterprise customers.

Disclosures

1: One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes). Actual user capacity may be less due to operating environment.
2: Advanced Format drive: 4K (4096-byte) physical sectors.
3: Portion of buffer capacity used for drive firmware.
4: Based on internal testing; performance may vary depending on host environment, drive capacity and other factors. 1MiB = 1,048,576 bytes (220), 1MB = 1,000,000 bytes (106).
5: Projected values. 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 220TB/year and temperature 40C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year and 60°C ambient (65°C device temp). MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
6: SATA models: Random RW 50/50 8KB QD=1, SAS models: Random RW 50/50 4KB QD=4.
7:Idle specification is based on use of Idle_A.

1: One megabyte (MB) is equal to one million bytes, one gigabyte (GB) is equal to 1,000MB (one billion bytes), and one terabyte (TB) is equal to 1,000GB (one trillion bytes) when referring to storage capacity. Accessible capacity will vary from the stated capacity due to formatting, system software, and other factors.
2: Advanced Format drive: 4K (4096-byte) physical sectors.
3: Portion of buffer capacity used for drive firmware.
6: MTBF and AFR targets are based on a sample population and are estimated by statistical measurements and acceleration algorithms under median operating conditions. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
7: SATA models: 8K Queue Depth = 1 @ 40 IOPS, SAS models: 4K Queue Depth = 4 @ Max IOPS.
8: Idle specification is based on use of Idle_A.
