Three 2.5" SAS Drives: Enterprise Data Giants, Compared

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: Access Time And I/O Performance

Due to their higher spindle speeds, the Hitachi C10K600 and Seagate Savvio 10K.5 access data more quickly than the Seagate Constellation.2.

The benchmarks show that Hitachi improved the Ultrastar C10K600's I/O performance. The Ultrastar delivers a performance on par with that of 15 000 RPM drives, making it the fastest 10 000 RPM drive. The two Seagate drives, especially the Constellation.2, are not intended for intensive I/O operations.
