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 3151MB/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:

Don’t Get Fooled
Because we’re widely considered the Thunderbolt experts, we must know all the little details that others purposefully overlook or hide. For a bus-powered enclosure to be Thunderbolt certified, it must meet Intel power certifications. As such, speeds are limited to 1500MB/s. While many no-name brands claim to be USB4, they are in fact Thunderbolt 3 solutions that do not follow Intel specifications. Unlike those budget brand pretenders that will leave you feeling fooled and disappointed in far lower speeds, the Express 1M2’s true USB4 connectivity assures you of an astounding doubling of Thunderbolt’s speed.

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.

Professional Grade = Ready to Work
We understand having confidence in gear reliability is paramount to creative professionals. That’s why every Express 1M2 undergoes OWC's multi-hour "burn-in" performance certification prior to shipping. This ensures your Express 1M2 arrives operating properly and immediately ready for demanding use.
