What type of storage is described as non-volatile and can only be overwritten a limited number of times?

Flash memory is a type of storage that is non-volatile, meaning it retains data even when power is turned off. This characteristic makes it particularly useful for devices like USB drives, SSDs (Solid State Drives), and memory cards. The limited number of write and erase cycles is a defining feature of flash memory; typically, flash memory can be rewritten about 10,000 to 100,000 times before it starts to wear out and become unreliable. This differentiates it from magnetic storage, which can be overwritten an unlimited number of times, optical storage, which is often read-only or requires special processes to rewrite data, and cloud storage, which is a service that relies on remote servers rather than being tied to any specific type of physical storage medium.
