Hardening flash storage for ultimate data security - Story
April 14, 2017
Today's flash storage has made it possible to make embedded systems lighter, faster, more energy-efficient, and more compact than ever. With no moving parts, their reliability is unrivaled and they're the perfect storage medium for rugged applications. However, the nature of flash also makes it more difficult to erase data securely than with traditional magnetic storage. Modern wear-leveling algorithms designed to maximize drive life are extremely effective, but also make it difficult to encrypt files individually or ensure data is ever completely erased. All is not lost: Whole-drive encryption enables engineers to provide strong data security, even with modern flash drives. For military applications its benefits are clear, for both securing data as well as securely erasing sensitive data at the push of a button.
