<p>In contrast, multi-level cells (MLC), triple-level cells (TLC), and quad-level cells (QLC) store more data per cell but have lower performance and endurance. SSDs using <a href="page.php?w=3D_XPoint">3D XPoint</a> technology, such as Intel's Optane, store data by changing electrical resistance instead of storing electrical charges in cells, which can provide faster speeds and longer data persistence compared to conventional flash memory. SSDs based on <a href="page.php?w=NAND_flash">NAND flash</a> slowly leak charge when not powered, while heavily</p><p>
