Western Digital 12TB Ultrastar DC HC520 HDD. Driving up Capacity and Driving Down TCO

The Ultrastar DC HC500 series SAS or SATA HDD are-series is designed for public and private cloud environments where storage density and cost-efficient infrastructure is critical.

More Value to the Data Center with Capacity, Power Efficiency and Reliability
Laying the foundation for a worry-free data center, Western Digital delivers 12TB capacity drive to conquer the data explosion – Ultrastar® DC HC520, previously known as Ultrastar He12 and part of our HC500 series of helium-filled hard drives. Designed to handle workloads up to 550TB per year, the Ultrastar DC HC520 is the industry’s first 12TB1 drive and uses traditional perpendicular magnetic recording (PMR) technology to make it dropin ready for any enterprise-capacity application or environment. The stable internal environment created by fourth-generation HelioSeal®  technology enables a new 8-disk design, increasing the capacity by 20% when compared to the 7-disk design of the prior generation, Ultrastar DC HC510. This high capacity helium drive offers one of the lowest power profiles in the industry to help data center architects meet eco-environmental goals and requirements. Targeted at 2.5M hours MTBF2, the Ultrastar DC HC520 provides the highest reliability rating available of all HDDs on the market today by building on the successful design of its 10TB, 8TB and 6TB predecessors. Trust Western Digital and the Ultrastar DC HC520 to deliver more capacity, more efficiency, more reliability and more value to your data center.

HelioSeal Technology Helps Solve Challenges Facing Next Generation Data Centers
Data centers are facing growing pressures. Data volume is expanding, operating costs are rising, yet budgets remain flat. Lowering the total cost of ownership (TCO) has become the focus of data center architects and the Ultrastar DC HC520 provides the best value proposition and greatest storage efficiency available. Compared to 8TB Ultrastar air-filled drives, this HelioSeal hard drive provides 50% more capacity, uses 52% less power (Watts/TB), and is 25% more reliable, rated at 2.5M hours MTBF. Datacenter ready features like a second generation dual-stage actuator—the Western Digital Micro Actuator—enhance head-positioning accuracy to deliver better performance, data integrity and overall drive reliability, especially in multi-drive environments where operational vibration is present. Refer to our technical brief to learn more. A choice of 6Gb/s SATA and 12Gb/s SAS interface enables easy integration into high performance data centers.

  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 object storage methodologies, formatting, system software, and other factors.
  2. 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.
  3. Advanced Format drive: 4K (4096-byte) physical sectors
  4. Portion of buffer capacity used for drive firmware
  5. MiB/s is 220 bytes, MB/s is 106 bytes
  6. Excludes command overhead
  7. SATA models: 8KB Queue Depth = 1 @ 40 IOPS, SAS models: 4KB Queue Depth = 4 @ Max IOPS
  8. Idle specification is based on use of Idle_A
