Then changes are written to a separate file map. Wear leveling re-shuffles the data to ensure even wear across all blocks. Each write process causes the memory to degrade or “wear” a little. Like the MHD, it also uses a file system to communicate data storage locations to the host system. Instead of writing to a location on a physical disc, information is written to a memory block. The operating system (OS) indexes the file location in a file system and accesses the data using a mechanical arm.Īn SSD is a type of flash memory. A mechanical hard drive (MHD) stores data in physical locations on a magnetic platter. This is a first defense that evenly distributes stored data between SSD blocks to ensure even wear. Which means you should never have to perform routine maintenance on an SSD. The hardware is endowed with a series of algorithms and protective measures, like ‘wear leveling’ and ‘TRIM support’ to maximize drive life and ensure that data is discarded correctly. SSDs are designed to be self-sufficient generally rendering a secure erase redundant. Conclusion Will Securely Erasing Your SSD Damage It?.Is Securely Erasing Your SSD Something You Should Do Often?.
