Products using NAND FLASH memory chips, constitute a separate product group due to their characteristics and intended use. Thanks to the FLASH memory, they do not lose data when the power supply is disconnected which predisposes them to use as a permanent storage media. Depending on the type of flash memory products vary in durability, speed and capacity. Currently, there are products containing NAND FLASH type: SLC, pSLC, MLC, TLC. This group consists of:
- USB memory
- Flash memory cards
- Drives Solid State Drive (SSD)
Depending on the type of products are implemented different mechanisms to ensure product stability and security. Each product in this group has a mechanism of data correction, and even wear flash memory and given the number of write cycles is counted in the entire memory capacity.
