NAND is subject to two competing factors relative to temperature. At high temperature, programming and erasing a NAND cell is relatively less stressful to its structure, but data retention of a NAND cell suffers. At low temperature, data retention of the NAND cell is enhanced but the relative stress to the cell structure due to program and erase operations increases.
The best way to optimize the data retention of a NAND-based SSD is to limit the temperature at which the NAND flash is stored. When the drive has reached or is approaching its end of life, limiting the time of exposure to high temperature will also help extend the data retention. |
