Solid State Drives on the IBM System Storage DS5000 series
This appendix describes Solid State Drives (SSD), which are supported by the IBM DS System Storage with the DS5000 storage subsystems. We compare this technology to hard disk drives (HDD), and we base this comparison on tests we ran that compared SSDs to HDDs. Lab tests show a significant performance advantage with SSDs with a substantial reduction in the number of drives needed to meet the desired level of performance. Fewer drives translate into a smaller physical footprint, reduced energy ...
