Tom’s Hardware - Client SSDs: Samsung Retains No.1 Spot, SSDs Outsell HDDs by 2.6x
 
“Shipments of solid-state drives in the second quarter of 2021 remained almost flat, due in part to a slight sequential decline in PC shipments in Q1 and to ever looming shadow of component shortages. Unit wise, SSDs outsold hard drives by 47% as most client systems now use solid-state storage, but HDDs lead in terms of capacity by 411% as they are used to store the majority of data generated today. Samsung remained the world's largest supplier of SSDs followed by Western Digital, and Kioxia.
 
The industry shipped 99.6 million SSDs in Q2 2021, up slightly from 99.438 million drives in Q1, according to Trendfocus (via StorageNewsletter). By contrast, three makers of HDDs shipped 67.6 million hard drives with a capacity of 350.7EB. 
 
Client SSDs commanded the largest share of shipments with 86.86 million drives sold in the second quarter of 2021, up 1.7% from Q1 2021. Meanwhile, sales of PCs in the second quarter totaled 83.614 million units (according to IDC), down slightly from 83.981 million PCs in Q1 2021.”
 
SSDs have almost become the standard storage medium on client systems. 
 
Now if only 4TB SSDs pricing would come down, then I would be happy.
