Wear leveling (also written as wear levelling) is a technique for prolonging the service life of some kinds of erasable computer storage media, such as flash memory, which is used in solid-state drives (SSDs) and USB flash drives, and phase-change memory. There are several wear leveling mechanisms that … See more EEPROM and flash memory media have individually erasable segments, each of which can be put through a limited number of erase cycles before becoming unreliable. This is usually around 3,000/5,000 cycles … See more • Flash file system • Battery balancing See more • Flash SSDs – Inferior Technology or Closet Superstar?, bitmicro.com, archived from the original on February 2, 2007 See more There are three basic types of wear leveling mechanisms used in flash memory storage devices: No wear leveling See more There are several techniques for extending the media life: • A checksum or error-correcting code can be kept for each block or sector in order to detect errors or … See more WebDec 5, 2008 · Flash Drives ARE NOT Indestructible. USB Flash Drives are susceptible to wear and tear, static shock and power fluctuations. One frequent killer of USB Flash drives is removal during a write operation. This can cause corruption to the internal wear leveling tables that tell the controller where each sector is stored on the NAND flash chip. To ...
