About this product
Data center decisions are driven by TCO. Higher capacity hard drives play a leading role in reducing TCO. An 18TB data center HDD provides 29% more capacity in the same form factor as a 14TB HDD. Higher capacity HDDs enable data centers to lower CapEx by reducing supporting hardware and system level costs when compared to lower capacity drives. Helium-sealed, low power, high reliability drives reduce energy and maintenance costs, contributing to OpEx savings.
- Helium platform data center hard drive
- 12Gbps transfer rate provides compatibility with high-performance data centers
- 3.5" form factor
- Industry's first HDD with Energy-Assisted Magnetic Recording technology
- Self-encrypting drive options
- 5-year manufacturer limited warranty
