Compact embedded systems are becoming smaller, while storage requirements continue to grow. Applications such as embedded computing, medical computers, self-service kiosks, and service robots need reliable local storage for operating systems, data, logs, updates, and system files.

However, when system space is limited, adding storage is often not as simple as installing another SSD. Designers may face limited PCB space, low-profile enclosures, and a lack of available M-Key storage slots.
