Hard disk won’t go away because of the market that’s very hungry for storage. In the age of data, you need lots of storage. Having said that, retail users generally don’t need that much hard disk space and we can see that sales have been declining. With MS looking to eliminate mechanical drive in the next few years, retail demand for hard drives will take a dive. Ultimately, it’s these companies may consolidate further. In my opinion, both WD and Toshiba are better positioned since they are also active in manufacturing SSDs. While Seagate produces SSDs as well, but I think they market penetration may not be anywhere near WD and Toshiba.
