Product Features
- 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. 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. 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.
Special Fetures
- Reliable, field-proven design
