### **Understanding SSD Technology**
Unlike HDDs, which rely on spinning platters and mechanical read/write heads, SSDs use flash memory to store data electronically. This difference in design makes SSDs significantly faster and more reliable. Key components of SSDs include:

1. **NAND Flash Memory**: The primary storage medium in SSDs, consisting of memory cells that retain data even when powered off.
2. **Controller**: A chip that manages data storage, retrieval, and error correction, ensuring optimal performance.
3. **Interface**: SSDs use interfaces like SATA (Serial ATA) or NVMe (Non-Volatile Memory Express) to connect to a system’s motherboard, with NVMe offering superior speeds due to its direct communication with the CPU.

By eliminating the moving parts found in HDDs, SSDs reduce the risk of mechanical failure and enable rapid access to stored data.
