Higher performance and redundancy for high-capacity SAS architectures
Web 2.0 storage applications have been a boon to high capacity server-class SATA drives like Seagate’s Barracuda ES. But 7200 rpm SATA will only take you so far. Enterprise-class 15K rpm SAS drives are incredibly robust and full-featured, and priced like it. Shouldn’t there be something in between?
Now there is. Seagate has added a SAS drive to the Barracuda ES family. It costs a little more than the SATA version, but gives back dual ports and more than twice the performance in some applications, along with the 1 TB capacity.
Conventional wisdom is that performance is determined by spin speed. Don’t overlook the power of SAS to jack up the speed of your high-capacity applications.
So what’s the consensus out there – does performance matter? There is some thought that would says that speed on HDD’s hasn’t kept up with capacity

– while this may help mitigate that trend, is it enough to matter?
