Thats the point. You talk about old devices. Those are based on SLC
flash. SLC (NOR) flash is OK. E.g. Atmel guarantees a data retention
time of 100 years for the flash in AVR microcontrollers. Currently as
new available SD cards are MLC and increasingly TLC (NAND) flash. MLC is
problematic and TLC even more.
