We see a sum total of about four to eight SATA ports on most consumer motherboards, which effectively limits the number of drives you can have in a machine. In all this time, sadly, the ports offered by most motherboards haven’t changed. We have been warned not to expect further capacity increases to fall in price as quickly, due to the technical challenges involved in even larger drives. It is clear that we are beginning to reach the limits of perpendicular recording technology – the technology that saved us from the 320-500Gb/drive brick-wall. They are intended for use by system integrators for high end, data-center applications. The larger 5Tb and 6Tb drives have an astronomical price-tag to match, and Hitachi even resorts to helium-filling the drives to make it a possibility. Space demands continue to rise, although hard disk capacity growth has slowed somewhat.įor a long period, we were saddled with only 2Tb and 3Tb drives, and only recently have 4Tb, 5Tb and 6Tb drives emerged. This is true more than ever, with the proliferation of high definition multimedia files, high resolution digital photography, graphically intensive games and even software defined radio. A universal truth since the beginning of computing has been that you can never get enough storage because you’ll always find something to fill it with.
