The advent of Solid-State Drives (SSDs) has significantly impacted various aspects of computing, including database design. With their much faster read and write speeds compared to traditional Hard Disk Drives (HDDs), SSDs have opened up new possibilities for optimizing database performance.

Based on 2 community responses
The introduction of SSDs has changed database design in several key ways. Firstly, SSDs have reduced the importance of sequential access patterns, allowing databases to be designed with more random access in mind. This has led to the development of new indexing techniques and data storage layouts that take advantage of SSDs' fast random read and write capabilities. Additionally, SSDs have enabled the use of more aggressive caching strategies and have reduced the need for complex query optimization techniques that were previously necessary to minimize disk I/O.
