By , published

Currently, 2.5" enterprise drives are leaving their 3.5” competitors behind. They're faster, more flexible, and now they offer comparable capacities (we're up to 1 TB now). In this piece, it's Hitachi versus Seagate battling for high-density supremacy.

Benchmark Results: Power Efficiency

The performance per watt for streaming read workloads looks great for both the Hitachi Ultrastar C10K600 and the Seagate Savvio 10K.5. Both deliver high throughput, while maintaining relatively low power consumption.

Because of its optimized  I/O performance, the Hitachi drive easily takes the prize for performance per watt at typical workstation loads.
