Quote:Today we have one interesting research in our hands. According to Trendfocus inc. we have come to know that as much as 333 million Solid State Drives were shipped last year, in 2020. The SSDs have finally overcome HDDs in the number of shipped units, with HDDs shipping 260 million units. In terms of total capacity shipped, HDDs are still winning. The average SSD has less storage capacity compared to the average HDD, thus making the total shipped capacity of all 333 million SSDs "just" 207 Exabytes (EB), while the total shipped capacity of HDDs is a bit over one Zettabyte (ZB).

The average capacity of SSD was as much as 0.67 Terabytes (TB), while the average capacity of HDD was around 4.0 TBs. This is exactly why HDDs are still present as much - simply because they can store much more storage and offer better value as the price per Gigabyte ratio is much lower than the one of an SSD. The SSDs are experiencing Year-over-Year growth of 20.8% in unit shipments, while HDDs are declining at the rate of 18%. When it comes to the total storage capacity shipped on yearly basis, SSDs are growing at the rate of 50%, with HDDs growing at a 13% rate.
