Certified Windows To Go drives were high-performance USB sticks designed to handle the heavy read/write cycles of a full operating system. While most manufacturers have stopped producing them, you may still find remaining stock or used units of formerly certified models:
: High-end drives tested for cryptographic standards.
: Third-party sellers on platforms like eBay and Amazon sell pre-configured USB drives labeled as "Portable Windows Workstations". Note: These often require your own product key for activation.
