On the other hand, SSDs use flash memory to store data, providing faster access times and lower latency compared to SATA hard drives.
How SATA Hard Drives Work
SATA hard drives consist of a spinning disk, a mechanical head, and a motor. The disk is divided into tiny sectors, each storing a small amount of data. When you save a file, the mechanical head moves to the correct sector and writes the data onto the disk. The motor spins the disk at a high speed, allowing the head to access different sectors quickly. SATA hard drives are available in various storage capacities, ranging from a few hundred gigabytes to several terabytes.
How SSDs Work
SSDs, on the other hand, use flash memory to store data. They consist of a controller, memory chips, and an interface. The controller manages the flow of data between the memory chips and the interface, which connects the SSD to the computer. When you save a file, the controller writes the data to the memory chips, which store the information in a series of interconnected flash memory cells. SSDs are available in various storage capacities, ranging from a few hundred gigabytes to several terabytes.
