How Does an SSD Work?

To understand how a solid-state drive (SSD) works, let’s take a closer look at its internal components and the process it uses to store and retrieve data.

At the heart of an SSD are NAND flash memory chips. These chips are organized into a grid-like structure, with each cell capable of storing multiple bits of data. The data is stored in these cells by applying electrical charges to specific transistors within the NAND flash memory.

In an SSD, the flash memory cells are divided into pages and blocks. A page is the smallest unit that can be read from or written to, usually ranging from 4KB to 16KB in size. Multiple pages are grouped together to form a block, usually 128 pages or more.

When a computer sends a read request to the SSD, the controller identifies the specific location of the data and retrieves it by accessing the appropriate pages and blocks. This process of retrieving data is much faster in SSDs compared to traditional hard disk drives (HDDs) because there are no mechanical parts involved. The electrical charge stored in the cells is accessed directly, resulting in quicker read speeds.

When it comes to writing data, SSDs have a unique process called the “erase-before-write” mechanism. Unlike HDDs, which can overwrite data directly, SSDs must first erase data from the cells before writing new data. This is because writing new data to a cell that already contains data can cause interference and data corruption. Although this process may seem slower, SSDs make up for it with their overall faster performance during read and write operations.

In order to optimize the lifespan of the SSD and prevent wear on specific cells, SSD controllers employ a technique called wear leveling. This ensures that data is written evenly across the entire NAND flash memory, distributing the workload and preventing specific cells from being overused.

To manage the data stored on an SSD efficiently, the controller also utilizes a technique called garbage collection. When data is deleted or moved, empty pages are left behind. Garbage collection identifies these empty pages and consolidates the data, freeing up space and preventing fragmentation.

In summary, an SSD works by using NAND flash memory chips to store and retrieve data. The controller manages the writing, reading, erasing, wear leveling, and garbage collection processes, ensuring the SSD operates efficiently and maximizes its lifespan. With no moving parts involved, SSDs offer faster read and write speeds, improved reliability, and enhanced overall performance compared to HDDs.
