One of the hottest topics in storage is the adoption of solid state disks (SSDs) within external storage arrays. Over the last decade, advances in hard disk drive (HDD) capacity have far outpaced the random IOPS capability of HDDs, providing a catalyst for the increased adoption of SSDs. Inherent in the mechanical nature of HDDs is a latency that creates a significant bottleneck in the movement of data to and from the storage array. Common methods of improving the IOPS capability in storage systems include high-rotational speed HDDs and striping the data across additional disk drives, yet these approaches do not dramatically improve IOPS performance. Instead, they result in a dramatic increase in power consumption. SSD technology, by contrast, can vastly improve IOPS performance (by a factor of up to 1,000) while reducing total power consumption of a storage array.
