In recent years, the price gap between SSDs and HDDs has narrowed but it's still pretty large. While some believe SSDs will eventually get cheaper than HDDs, Seagate believes this is unlikely to happen in the coming years. At present a low-cost SSD costs about 20 times more per gigabyte than a low-cost HDD. The latter has a price per gigabyte of around $0.033 and Seagate believes it will be able to drive this down to half of a penny over the next five years.
“In fact, the disparity between the cost on a dollar per gigabyte is upper to 20 to 1 [right now],” said Dave Morton, senior vice president of finance at Seagate, at Citigroup’s global technology conference. “I personally will never foresee the day, […] when there is a crossover [between the per-gigabyte cost of NAND and rotating magnetic media]. In 2020 we [will] have drives in the portfolio that will be less than half a penny per-gigabyte. I just don’t see how you could get that from the competing technology.”
