Flash storage is a type of non-volatile memory that retains data even when the power is turned off. It uses memory chips to store information, making it faster and more durable than traditional hard drives. Common forms of flash storage include USB drives, solid-state drives (SSDs), and memory cards. One of the main advantages of flash storage is its speed, allowing for quick data access and transfer. Additionally, it is more resistant to physical shock, which makes it ideal for portable devices like smartphones and tablets. Its compact size also enables higher storage capacities in smaller devices.
