StorageNewsletter.com has reported that SSD shipments exceeded HDD shipments in 2020. Over 333 million SSDs were shipped compared to 260 million HDDs in 2020. Something unusual happened in the enterprise sector, however: shipments of SAS SSDs declined by over 30 percent. This may be due to increased inventory and less demand. Total NAND capacity shipments also increased by 12 percent quarter over quarter, with SSDs consuming 45 percent of all NAND shipped.
Samsung led in Q420 with over 26 percent of total units shipped worldwide, accounting for over 32 percent of storage capacity. That equates to over 22 million units totaling nearly 18 exabytes of storage. The closest competitor was WDC with 20.3 percent shipped (15 percent storage capacity). Other competitors range from around 10 percent or less in both categories. Total SSD storage capacity for 2020 reached an all-time high of 207.39 exabytes.
