Despite ever-plunging per-gigabyte prices, storage device manufacturers are reporting banner profits each year. A huge part of the success comes from, of course, the storage device industry’s continual (and successful) adaptation of the hard disk drive (HDD) to our computing devices over the past 40 years or so. As our laptops, PCs, and servers have evolved over the years, becoming much faster, capable, and reliable, so have our HDDs.
Industry leaders, such as storage giant Western Digital, have not only reported record years recently, but they’re also predicting significant growth over the next five or six years. Western Digital, for instance, has estimated a two billion dollar surge, from $36 billion in 2013 to $38 billion by the end of 2014, in global, industry-wide storage-device sales. That is projected to grow by another four billion, to $42 billion, in 2015.
And this growth is in spite of a tremendous drop in the average cost per gigabyte. According to statisticbrain.com, over the past 33 years (from 1980 to 2013), the per-gigabyte cost dropped from $437,500 per GB to five cents per GB, respectively. That’s encouraging a rapid expansion in storage consumption, but technology must advance to keep pace.
