"Data Retention n Endurance in #NAND" chips mainly determined by Program-Erase (P/E) cycles
NAND flash memory chip in - USB-Drive, SDcard, SSD, mSATA, NGFF, NVMe (in order of slow>high tr speed)
Quality n Type of NAND finally matters depending purpose of use - mostly readonly or heavy read/write for data longivity NOTSPEED

3D NAND flash non-volatile memory devices could utilise MLC, TLC or QLC designs. NAND cells are not designed to last forever. Unlike DRAM, their cells will wear out over time as the write cycles are more taxing than read cycles. Low data density makes SLC the most expensive type of NAND. V-NAND, or 3D V-NAND is the latest technology in the flash memory world Also mSATA n NVMe sticks can be plugged using compatible adopter cards to USB for special portable use. M.2 is just physical formfactor size 2280 2242 (Samsung Hynix Intel)
