9.2.2.1 Design Requirements

In recent years, the size of Solid-State-Drives (SSDs) has increased rapidly, making it necessary to increase the number of flash memory devices in each drive. The flash memory devices sometimes share the same control and data channel to communicate with the controller. This causes increased loading to each communication channel as the number of flash memory devices increases. To meet the performance requirement of an SSD, the ability to isolate the loading becomes necessary.
