Many System Integrators\/developers are not aware of the “Endurance” limitations of MLC NAND Flash, and this can cause premature failure of entire fleets of IoT devices<\/a>. So, it is critical to measure how your software behaves and mitigate the issues associated with unsympathetic application software design when MLC NAND Flash is used or the primary storage device – especially one hosting a Linux OS & application software.<\/p>\n

 <\/p>\n

This white-paper is designed to help developers understand how to measure the impact of their software on an eMMC (NAND Flash) drive & what can be done if it appears that premature ‘wear-out’ is a risk for your application.<\/p>\n

This Whitepaper consists of 5 sections:<\/p>\n

    \n
  1. Introduction & author’s note<\/li>\n
  2. A brief note on eMMC vs SD Cards<\/li>\n
  3. Understanding “Wear” at\u00a0the physical layer<\/li>\n
  4. Measuring “Wear” from the host system<\/li>\n
  5. Measuring “Wear” at Drive level<\/li>\n
  6. The equation for NAND Flash wear\/endurance<\/li>\n
  7. General methods for Reducing & Managing “Wear”<\/li>\n
  8. Introducing Flash Manager<\/a> – Robustel’s<\/a> wear monitoring utility<\/li>\n<\/ol>\n
