Study Notes
Solid-State Drives (SSDs) Overview
- SSDs are a type of non-volatile storage device that uses NAND flash memory to store data.
- Unlike traditional mechanical hard disk drives (HDDs), SSDs have no moving parts, allowing for faster data access and improved reliability.
Key Differences Between SSDs and HDDs
- SSDs provide significantly faster data read and write speeds compared to HDDs, leading to quicker system boot times and file transfers.
- HDDs use spinning disks and a read/write head, making them slower and more susceptible to physical damage from movement.
- SSDs consume less power, improving battery life in portable devices.
Advantages of SSDs in Physical Characteristics
- The absence of moving parts in SSDs results in lower noise levels, less heat generation, and a lighter overall weight compared to HDDs.
- SSDs are more compact and can fit in smaller physical spaces, enhancing design flexibility for modern electronics.
Determinants of SSD Properties
- The type of NAND flash memory (e.g., SLC, MLC, TLC, QLC) influences endurance, speed, and capacity of SSDs.
- Controller technology impacts read/write performance and the efficiency of data management processes.
Cell Types in SSDs
- Single-Level Cell (SLC) technology is known for being the most reliable, durable, and fastest, but also comes at a higher cost.
- SLC stores one bit of data per memory cell, reducing error rates and increasing performance compared to Multi-Level Cell (MLC) and other types.
