The lifetime of a card depends on various factors: To handle this behavior, the card’s firmware includes several routines and assurance algorithms to replace damaged cells with spare cells. However, flash memory also has a few disadvantages: First and foremost, one has to note that the cells storing the bits only have a limited amount of write and erase cycles.
The most significant benefits of flash memory are its read and write speed, low power consumption and higher durability in harsh environments compared with mechanical disk drives. The camera negative of the digital era has some special characteristics caused by the NAND flash memory on which all memory cards and SSDs are nowadays based. Some insights into the life of a Flash memory So let’s begin by finding out why all flash memory has a built-in end of life by design. Finally, we’ll cut to the chase of the aforementioned worst-case scenario: What can you do when faced with a defective memory card? for checking a memory card’s state of health and provide a few care tips to help you elongate your memory media’s lifetime in the first place. We’ll also consider the possibilities of S.M.A.R.T. Everything we discuss below applies to any memory media used in SSDs or flash cards for cameras and sound recorders.įirst, we’ll establish a basic understanding of flash memory by discussing its unique characteristics and typical errors.
