Solid State Drives (SSDs) are increasingly being used as data storage media in computing, communication, and multimedia devices. Most SSDs use NAND flash memory as the storage media, which is capable of retaining data without any external power supply. A typical SSD consists of two main components: the data storage device itself (such as a NAND flash memory chip), and a controller for the storage device (such as a USB device controller in a USB flash drive) that acts as an interface for the SSD with the host system. The SSD controller manages the interfaces from both the host side (such as USB), and the device side (which includes mapping bad data blocks, caching read/write data, and error checking and correction, or ECC). The controller’s built-in ROM contains the firmware needed to control the drive. An SSD is an example of an embedded system, and needs a Real-Time OS (RTOS) for its operation. Several open source and proprietary firmware solutions are available for SSD controllers
