Lifespan aims to tackle the growing dependence on flash storage solutions. Understanding the remaining useful life of your solid-state drives and other flash storage devices can significantly enhance their performance and longevity. These devices are not designed to last indefinitely; their functionality can start to decline or cease altogether once they surpass their intended lifespan. Recognizing how much life is left is particularly crucial for devices subjected to heavy usage. Typically, flash storage employs non-volatile NAND solid-state memory for data retention, with each memory cell having a limited capacity for being ‘programmed and erased’. Depending on the type and quality of NAND chips, the number of program/erase (p/e) cycles a drive can endure may range from fewer than 2,000 to more than 10,000. For a standard solid-state drive, this generally equates to approximately 100 terabytes of usable life, highlighting the importance of monitoring usage to prevent unexpected failures. Regularly checking the health of these devices can ultimately lead to more informed decisions regarding data management and storage upgrades.
