Maximizing SSD Life Expectancy and Capacity

  • SSD storage costs are at an all-time low, with manufacturers utilizing various techniques to offer higher capacity drives at minimal costs.
  • Different types of flash storage impact SSD life expectancy, sustained write speed, and the presence or absence of D-RAM.
  • SSDs store data on flash memory chips in grids of cells, with two common technologies being floating gate and charge trap Flash.
  • Memory cells in SSDs can only sustain a limited number of program erase cycles before failing, with SLC drives lasting longer than MLC, TLC, and QLC drives.
  • SSDs now feature many layers of flash memory cells stacked on top of each other, known as 3D NAND or V-NAND, to increase capacity.
  • Wear leveling is a technique used in SSDs to maximize life expectancy by evenly distributing program erase cycles at the block level.
  • SSDs express their minimum life expectancy via terabytes written (TBW), with drive capacity affecting the rating, highlighting the importance of choosing the right SSD based on usage requirements.
