As Fast as Your Computer or Device

The Express 1M2 is the fastest single portable SSD we offer and was purposefully built to maximize the performance capabilities of today and tomorrow's USB4 equipped Macs and PCs. Experience up to an astonishing 3836MB/s speed when you use the Express 1M2 with most Macs and PCs you own from 2020 and newer. You can also enjoy highly effective performance (yep…you can edit 4K video no problem) and flexible compatibility with millions of yesterday’s Thunderbolt and USB-C machines and devices:

Express 1M2 Connected To... Runs As Real-World Speed
Any Apple Silicon M1/M2/M3/M4 Mac USB4 (40Gb/s) 3189MB/s
USB4 (40Gb/s) port on any PC USB4 (40Gb/s) 3836MB/s
Thunderbolt 4 port on any PC USB4 (40Gb/s) 3836MB/s
Thunderbolt 3 port on Intel Mac or PC USB (10Gb/s) 990MB/s
USB-C (10Gb/s) port on iPad, Mac, or PC USB (10Gb/s) 990MB/s

Don’t Get Fooled

Because we’re widely considered the Thunderbolt experts and work very closely with Intel, we know all the little details that others overlook. While specific OWC solutions are certified for full speed on Thunderbolt, we (and everyone else) are limited to half that speed with DIY enclosures. USB4 unleashes the Express 1M2 performance capabilities so you can build the drive of your dreams. Unlike budget brand pretenders that do not follow Intel specifications – and will leave you feeling fooled and disappointed with far lower speeds – the Express 1M2’s USB4 connectivity assures you of the maximum speed and reliability you count on and expect from every OWC solution.

The Power of DIY

Build your Express 1M2 with a brand-new drive. Retask an existing drive replaced during an upgrade. Or make it simple by choosing a pre-built proven OWC reliable solution. Whatever your decision, Express 1M2 gives you the power to make it happen.

Use Today’s and Tomorrow’s Drives

Designed to support any NVMe M.2 2230, 2242, or 2280 SSD, the Express 1M2 gives you the freedom of flexibility to use any drive today - including OWC Aura SSDs up to 8.0TB capacity - as well as being ready for tomorrow’s 16TB and future capacities without limit.

Built to Handle Demanding Needs

You’ll never have to worry about thermal throttling because form meets function with the Express 1M2. Its solid aluminum heat sink design ensures proper heat dissipation so you can depend on consistent maximum performance. Unlike a snap together toolless enclosure, Express 1M2 screws together to securely protect your drive inside its rugged enclosure. And when you need to share the Express 1M2, it can work cross-platform with Macs and PCs using OWC MacDrive software (available separately) for peace between the platforms.

The Power of Build Your Own Options

Build your Envoy Express with a brand-new drive for a fast boot drive. Retask an existing drive replaced during an upgrade for added storage and backup capacity. Or, use Envoy Express to regain access to files on a drive removed from an inoperable machine. Whatever the reason you want to build your own bus-powered Thunderbolt enclosure, Envoy Express gives you the power to make it happen.

Backup, Play, and Edit. Faster.

Whether you want to backup your growing photo and music libraries, share files, play your favorite games and movies anywhere, or even want to capture and edit up to 8K video, the Envoy Express can do it all. And it’s built to support super-fast sustained data transfer rates up to 1553MB/s…often faster than your machine’s internal drive performance!

Uses Today’s and Tomorrow’s Drives

Designed to support any NVMe M.2 2280 SSD, the Envoy Express gives you the freedom of flexibility to use any drive today — including OWC Aura SSDs up to 8.0TB capacity — as well as being ready for tomorrow’s 16TB and future capacities without limit.

OWC recommends OWC Aura P12 Pro NVMe M.2 SSDs up to 8.0TB

Gets Onboard with Macs and PCs

Today’s office is often a tiny bistro table, your lap in a remote location, or a cramped airplane seat. There’s no power outlet and not enough room for an external drive. Besides being the industry’s first Thunderbolt™ 3 bus powered (no power adapter required) enclosure, the Envoy Express is the first to include a laptop mounting system.

Removable adhesive gel and a lightweight yet durable plastic holder secure the Envoy Express onto the back of your Thunderbolt™ 3-equipped Mac or PC laptop screen. Easy to add and easy to remove with no marking or marring.
