How Does an SSD Store Data?
Understanding how an SSD stores data can provide insights into its data retention capabilities. Unlike traditional hard disk drives (HDDs) that use spinning disks and magnetic platters, SSDs utilize a different approach called NAND flash memory.
NAND flash memory is a type of non-volatile memory that retains data even when power is turned off. It is made up of memory cells organized in a grid-like structure, with each cell capable of storing multiple bits of information.
When you save a file on an SSD, the data is first converted into binary code, consisting of ones and zeros. Each binary digit, or bit, is then stored in a memory cell. The cells themselves are divided into pages, and a group of pages is organized into blocks.
To write data to an SSD, the existing data in a block must first be erased. This process, known as garbage collection, is performed by the controller of the SSD. The controller marks the blocks that are no longer in use as empty and prepares them for writing new data.
When new data is to be written, the controller determines the appropriate empty block and programs the necessary bits into the memory cells within the block. This allows the SSD to store the binary representation of the data you save.
But what happens when you modify or delete data on an SSD? Unlike HDDs, which can simply overwrite or remove specific sections of data, SSDs have a more complex process. In order to modify existing data, the controller must first copy the entire block of data to a new location, make the necessary changes, and then erase the original block.
This process, known as wear leveling, helps distribute the writing and erasing actions across the different blocks of the SSD, prolonging the lifespan of the drive. Wear leveling ensures that no single block is excessively used, helping to maintain the overall performance and longevity of the SSD.
In summary, an SSD stores data using NAND flash memory, where binary bits are stored in memory cells organized in pages and blocks. The controller of the SSD manages the process of writing, modifying, and erasing data, utilizing techniques such as garbage collection and wear leveling to optimize performance and ensure the longevity of the drive.
