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.Data durability and data security to support compliance and privacy requirements
As drive capacity grows beyond single-digit TBs, object storage systems with erasure coding provide better data durability compared to RAID systems, given its tolerance for simultaneous error conditions. The Ultrastar DC HC520 is a best-fit for object storage implementations with its massive capacity and unbeaten reliability rating. Compliance and privacy requirements drive the need for increased data security. The Ultrastar DC HC520 offers security and encryption options to help protect data from unauthorized use, including TCG SAS models.Western Digital quality and service
The Ultrastar DC HC520 extends Western Digital's long-standing tradition of reliability leadership with a 2.5M-hour MTBF rating. Ultrastar quality, capacity, power efficiency, and world-class technical support and service provide customers with a lower total cost of ownership over previous generations. Western Digital data center drives are backed by an array of technical support and services, which may include customer and integration assistance. Western Digital is dedicated to providing a complete portfolio of products and services to help create environments for data to thrive.Key selling points
- PMR technology works with all capacity enterprise applications & environments
- Reliable, field-proven, 4th generation design
- Outstanding power efficiency (Watts/TB)
- SATA 6Gb/s and SAS 12Gb/s - 12Gb/s SAS compatible with next-gen data centers; backwards compatible with 6Gb/s SAS
- 2.5M hours MTBF rating
- Instant Secure Erase (ISE) & Self-Encrypting Drive (SED) options
