NetApp has been getting a lot of questions about 15K RPM disk drives lately. As you may have heard, 3.5” LFF 15K RPM HDDs are being phased out by disk manufacturers. At the same time, 2.5” SFF 15K RPM disk drives face an uncertain future, and remain expensive.
Because of this, 2.5” 10K RPM disk drives have become a better option. These disks deliver twice the density in the same rack space, and they can be combined with SSDs in a Flash Pool aggregate that delivers great performance and capacity. Flash Pool provides more performance at a lower cost per GB, so you come out ahead.
2.5” SFF 15K RPM disk drives have not taken off to the same degree, and are not predicted to become a significant market force during the forecast period for a number of reasons:
So, if you’re in the market for performance disks, what options should you be considering? We compared 2.5” 10K RPM, 2.5” 15K RPM, 3.5” 15K RPM, Flash Pool (SSD plus 2.5” 10K RPM) and pure SSD configurations in the lab to come up with the best set of recommendations.
Currently, the economics of storage really make hybrid configurations the sweet spot. Hybrid storage offers a low cost per GB relative to 2.5” 15K HDDs, with great performance.
