An EEPROM is can be written/erased one byte at a time.
An SD card uses flash memory that can only be written in blocks, and can
only be erased in pages (which are typically larger than write-blocks).
Flash is typically many times cheaper than EEPROM, byte for byte, and
its block-structured nature is well suited for mass storage applications
whose filesystems are block-oriented anyway.
