Explore the concepts and techniques that are essential for designing, optimizing, and maintaining SSD (solid state drive) firmware. This book discusses the role of firmware in the functioning of SSDs and the importance of keeping firmware up to date to ensure optimal performance and security.
The book starts with an introduction to SSD firmware and its role in SSDs. You will then learn basic NAND operations and common firmware features, followed by various design considerations and best practices for optimizing and maintaining SSD firmware. Moving ahead, you will learn some of the advanced features that are included in modern SSD firmware, such as wear leveling algorithms, garbage collection algorithms, error prevention and correction methods, and algorithms to reduce write amplification. User data flow and exception handling are discussed next, along with performance and debugging. To wrap things up, you will gain insight into possible future developments and innovations inSSD firmware.
After reading this book, you will have a solid understanding of the key concepts and techniques that are crucial to designing, optimizing, and maintaining SSD firmware.
