Look beyond spin speed when evaluating SATA drive performance
Here’s a look at the Barracuda ES.2 SATA drive from Australian reviewer PC Authority. Many of today’s capacity intensive server applications require both TBs and IOPs. Depending on the application, both are available in a 7200 rpm SATA drive that can outperform a 10K rpm drive:
Amazingly, it managed to beat Western Digital’s Raptor – the King of Desktop Performance – in every aspect except seek times.
Of course there are serious applications that require more oomph than 7200 rpm SATA can provide. Thinking of performance and capacity in terms of spectrums of requirements rather than black and white needs will result in the most cost-efficient (and profitable) designs.
