By the 1990s, flash-based SSDs were introduced and started gaining popularity globally, but they were still costly (up to $47,000). Although this 2 GB SSD revolutionary creation still used core memory, it was highly compatible and operated much faster than fixed-head disks.Ĭompanies started developing SSD technologies, such as the Sharp PC-5000 with a 128 KB SSD bubble memory in 1983. However, those two solutions went out of style in the 1950s and 1960s with the growing popularity of cheaper storage components like drum memory.Īs technology is constantly evolving, by the 1970s and 1980s, SSDs were back on the scene, but they were pretty expensive and weren’t widely adopted until Dataram introduced the Bulk Core SSD in 1976.
