Did you know that the long road of SSD storage and its thailand whatsapp number data development began in the 1950s?

Yes, it is that old.

At that time, they were used in first generation computers ( vacuum tube computers ) through two similar technologies: card-based read-only storage and magnetic core memory .

However, both of these solutions fell out of fashion in the 1950s and 1960s with the growing popularity of cheaper storage components such as drum memory .

As technology is constantly evolving, SSDs made a comeback in the 1970s and 1980s, but they were quite expensive and did not see widespread adoption until Dataram introduced the Bulk Core SSD in 1976. Although this revolutionary 2GB SSD creation still used core memory, it was highly compatible and performed much faster than fixed-head drives.

Companies began developing SSD technologies, such as Sharp's PC-5000 with 128 KB SSD bubble memory in 1983. In the 1990s, flash-based SSDs were introduced and began to gain popularity worldwide, but remained expensive (up to $47,000).
