How does an SSD work?

SSDs are modern storage devices that use flash memory tech to store and access data. Unlike HDDs, they have no moving parts, making them more reliable and faster. The secret of SSDs is in its memory chips, which save info using electric signals. These chips are arranged in a “NAND array” of floating-gate transistors, that hold electric charges. By manipulating those charges, data can be written, read, or erased.

When saving a file on an SSD, it is divided into small parts and stored across the NAND array. This process is called “wear leveling”, to make sure data is spread over the drive and doesn’t wear specific areas too much. When the file needs to be accessed, the SSD retrieves the parts and puts them back together quickly.

To read data from an SSD, the controller sends a charge to specified transistors in the NAND array. They respond with current flow (1) or no flow (0), then the controller interprets the responses into digital info for the OS.

What makes SSDs different from HDDs is their speed. With no mechanical parts, SSDs can access and retrieve data much faster than HDDs. That results in faster boot times, shorter app load times, and better system performance. SSDs also have better durability than HDDs. No moving parts mean they can handle shocks, vibrations, and extreme temperatures better, so your data is safer.
