That article also raises some further questions regarding its validity.
Firstly, there's been a declared fall in PC sales, which clearly include laptops, as everyone is saying that tablets and smartphones are taking over. Noting that most tablets (for at least the last year or more) already come with an SSD fitted and most don't have the ability to change the hard drive, so where is this increase in SSD sales actually being generated? The Microsoft Surface Pro hasn't been released, so these can't be included in the supposed increase.
Secondly, given that some tablets do allow the hard drive to be exchanged, there are not a great many manufacturers that make 7mm, or thinner, SSDs that are able to fit into a tablet. Desktop/laptop users have traditionally been the ones changing and upgrading hard drives and the biggest sales seem to be in the traditional 2.5" form factor SSDs (9.5mm), which desktop and laptop users buy.
Thirdly, enterprise users have been the most significant group to take up SSD use over the last year or so and continue to do so, as capacities, speed and reliability increase, and costs reduce. So has the increase in SSD sales quoted in the article been somewhat misplaced as to the reason?
