Why do SD cards fail?
Accumulation of Bad Blocks: Just like the hard drive, the SD cards tend to develop bad blocks as they age. The bad blocks are the bad storage space where the data cannot be stored anymore. With time, the bad blocks keep on accumulating and reduce the performance level of SD cards.
What is a CF card slot?

Is the SD card still the best memory card?
However, SD is still the card of choice for some lower-end cameras, prosumer cameras, and consumer-level cameras. But the thought that was on some photographers’ minds was whether the SD card could be improved for greater capacity and transfer speed.
What can a SD card be used for?
Secure Digital memory cards (SD Cards) are used in just about every type of portable device available, from digital still cameras, video cameras/camcorders, tablets, to cell phones and smartphones.
