The 1-terabyte OWC Envoy Pro EX ($469.99) is a durable solid-state drive (SSD) for design-conscious users who need a lot of storage with speedy transfer rates. It's a lot faster, and a lot more expensive, than portable hard drives like our top pick, the Seagate Backup Plus Portable . 

Design and Features
Built into an anodized aluminum enclosure that feels like a solid ingot, the Envoy Pro EX bears a matte silver finish that matches that of the Apple MacBook Air and MacBook Pro laptops perfectly. But the drive also complements Windows laptops like the HP Spectre x360 15t. It measures 0.44 by 2.13 by 4.5 inches (HWD) and weighs 2.88 ounces, so it will fit in your front jeans pocket. It's a little larger than the Samsung Portable SSD T3 , but much smaller and lighter than traditional portable drives like the Seagate Backup Plus Portable. There are rubber feet on the bottom of the drive to keep it in place, with an activity LED on the front face, and a micro-USB-3.0 connector on the back. The drive's USB cable is included, and removable.
