Merk:
HGST (Hitachi)
Artikelcode | HUC109090CSS600 |
Informatie
Ultrastar™ C10K900 is a 2.5-inch 10,000 RPM hard drive that leads the industry with 18% faster sequential and up to 17% random performance than the nearest competitor. The highperformance SAS 6Gb/s interface delivers data reliability, availability and scalability and is the only small form factor SAS drive in the industry to pack a 64MB cache buffer for optimized read/write response time.
Highlights
- Built on field-proven, reliable design
- Industry-best performance in a 10K RPM 2.5-inch form factor
- 18% faster sequential and up to 17% better random performance than competition
- Uses 28% less power during operation than competition
- 900GB capacity continues to support the 3.5- to 2.5-inch form factor transition
- High-performance 6Gb/s SAS for reliable data throughput
- Large 64MB cache buffer manages data efficiently
- Halogen-reduced design and industry-best power utilization for most eco-friendly 10K SFF hard drive
