The OWC Envoy Express is the world’s first Thunderbolt™ certified ‘add your own drive’ bus-powered enclosure for super-fast pocket-sized video, photo, audio, and gaming backup and storage. Shorter than a pen and weighing just 3.3 ounces, the rugged anodized aluminum pocket-sized enclosure with integrated Thunderbolt 3 cable provides a DIY easy install of an M.2 NVMe SSD and supports sustained data transfer rates up to 1553MB/s. When workspace is limited, an included surface-safe removable drive holder secures the sleek and silent Envoy Express onto the back of a Thunderbolt™ 3-equipped Mac or PC laptop screen for out-of-the-way use convenience.
