The capacitor doesn&#x27;t itself significantly increase the price but there are more differences than just a capacitor in the datacenter drives. Look at the power consumption for the start, DC ones use much more power on idle. Also look at the technology behind: DC variants have to be more conservative with the stress to the cells (less bits per cell, potentially less cells per area, potentially more spare cells to replace died ones etc).<p>And the market segmentation is the natural way to go. The different needs and different sensitivity to price determine the price.
