Three 2.5" SAS Drives: Enterprise Data Giants, Compared

Features
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: Temperature And Power Consumption

Thanks to its lower spindle speed of 7200 RPM, the Seagate Constellation.2 stays cooler than both of the other drives.

In idle, the Hitachi Ultrastar C10K600 runs with the least power, but the two Seagate drives are also convincing with moderate values not exceeding 5.2 W. The power consumption of all three test candidates rises little, even at maximum data throughput. However, the Seagate Savvio 10K.5 uses more power than the other devices in the test bed.
