Reasons for SD Card can not Format and Even Unrecoverable
NAND Flash | SLC - Single Level Cell | MLC - Multi-Level Cell | TLC - Triple Level Cell |
---|---|---|---|
Read/Write Cycles | 90,000-100,000 | 8,000-10,000 | 500-1000 |
Bit Per Cell | 1 | 2 | 3 |
Write Speed | ★★★★★ | ★★★☆☆ | ★★☆☆☆ |
Endurance | ★★★★★ | ★★★☆☆ | ★★☆☆☆ |
Cost | ★★★★★ | ★★★☆☆ | ★★☆☆☆ |
If the read/write cycles of TLC is 500 times, how long can we use the SD card? If you save files to SD card for 1-2 times, files system of the SD card will be modified 3-4 times per day. The life of the SD card will last for about 250 days. However, if the quality of flash memory in SD card is poor, the life of the SD card will be shorter.
You may confuse here. 500 read/write cycles is for single cell. Data saving in the SD card will not save in the same cell. The life of the SD card should be longer. However, SD card is different from HDD. If one cell fails, whole SD card fails. Writing data to SD card will change the information in the file system for 1-2 times at least. Once this information saving cell reach the read/write cycles, whole SD card will fail to work and users can only read data inside. Some even can not be recognized.
Besides, the size of SD card is tiny and can not use the controller chips with the effective asymptotical algorithm of load balance. This algorithm make a longer life of SSD with same TLC flash memory in SD card.
