SSD Failure refers to the malfunction or breakdown of a Solid State Drive, a type of storage device that uses flash memory to store data. Unlike traditional hard drives, SSDs have no moving parts, which generally makes them more reliable. However, they can still fail due to factors like electrical issues, firmware bugs, or wear and tear from extensive use. When an SSD fails, it can lead to data loss, making it crucial to have regular backups. Signs of impending failure may include slow performance, frequent crashes, or error messages. Monitoring tools can help detect issues early, allowing users to take preventive measures.
