WebFTL is a hardware and software layer, situated in the controller of peripherals based on flash memory, such as SSDs, USB keys, SD/MMC cards and eMMC chips. One of the roles of the FTL is to emulate a block-type peripheral. The concerned peripherals can thus be used the same way as hard disk drives are.
