Samuel Clemens (better known as Mark Twain) already said that «the news about my death has been somewhat exaggerated» . And probably many would think that by now the traditional, mechanical hard drives, those of all life, were something residual, minority and on the way to extinction. They are wrong.

And it is that throughout 2020 more than 139 million hard disk drives were sold , a figure lower than the sales during the previous year although, in return, what increased was the storage capacity of those that were sold. These hard drives have less and less room in the progressively ultra-thin designs of laptops (why speak of tablets or smartphones. In addition to space they are losing the battle to solid-state memory for speed and power consumption.

However, there were still 84 million traditional hard drives that during 2020 were destined to equip laptops . In some cases as an individual storage unit, in others as a complement, by combining SSD storage for the operating system together with frequently used programs and data, the hard disk being reserved for data storage.

In return, desktops and servers continue to use traditional hard drives in a significant proportion, as shown by the total of the two types of these storage devices in 2020 reaching 259 million units.

Seagate, the leader

Regarding the ranking of the sector, the market share of the main manufacturers is as follows:

  • Seagate: 42% (110 million hard drives)
  • WD: 37% (96 million hard drives)
  • Toshiba: 20% 42% (52 million hard drives)

It is worth noting that more than 49 million hard drives were destined for non-strictly computer devices: game consoles, home media recorders and especially portable and external hard drives.
