Which type of flash memory card is currently the most popular?

The CompactFlash, Memory Stick, Secure Digital, and xD cards are currently the most common cards used for digital cameras. NAND Flash architecture is one of two flash technologies (the other being NOR) used in memory cards such as the CompactFlash cards.

What is the fastest SD card class?

Cards can be rated as Class 2 (minimum write speed of 2MB/s), Class 4 (4MB/s), Class 6 (6MB/s) or Class 10 (10MB/s). It’s important to note that these are the minimum, so it’s entirely possible a card can achieve faster speeds but these give you an impression of the least you can expect.

What is difference between flash memory and eeprom?

is a type of memory where data is read, written, and erased at the byte level. Flash memory, on the other hand, which is a type of EEPROM, is architecturally arranged in blocks where data is erased at the block level and can be read or written at the byte level.
