Additionally, optimized server architectures are taking advantage of the benefits of (SSDs). Exploiting NAND flash technologies, SSDs are aiding optimized servers to further curtail power use and cutting associated cooling costs. With digital design and no moving parts, SSDs save much more power than traditional hard disk drives (HDDs). In comparison to a conventional 15K rpm HDD, certain SSDs can use only 1.7W in active mode for a 79% drop in power consumption. Power savings in the idle mode is even greater -- about 83% compared to a 15K rpm HDD.

Another measure of performance is the number of inputs and outputs per second per watt or IOPS/W. In this metric, the Green SSDs outperform the traditional 15K rpm HDDs by a huge margin. Internal tests demonstrate that second generation Green SSDs IOPS/W are 200 times higher than a 15K rpm HDD. In addition, the SSDs occupy considerably less space, and depending upon the application, a single Samsung SSD can replace between four and 40 15K rpm SAS HDDs in a server array.

Few will argue that quick payback for both Green DRAM and SSDs matters a great deal, and upon close examination, even fewer will argue about the overall cost-saving impact of Green DDR3 and Green SSDs in substantially shortening most data center's ROI.
