Our editorial take on the OWC Atlas USB4 CFexpress Type B Card Reader
The OWC Atlas USB4 CFexpress Type B reader is a direct response to the primary bottleneck creative professionals face: offloading data. It's not just an incremental update, it's a fundamental shift in transfer capability that leverages the full power of the USB4 and Thunderbolt interface. While older USB 3.2 readers have become a frustrating speed bump, this reader unlocks the potential of next-generation CFexpress 4.0 cards, translating benchmark numbers into real, tangible time savings. For anyone shooting high-bitrate video or high-resolution photo bursts, this is the tool that gets footage from your card to your timeline with astonishing speed.
Of course, achieving these peak speeds requires a complete, modern hardware chain. You will not see the full 4x performance gain over older readers without a computer equipped with a USB4 or Thunderbolt port and, just as importantly, a CFexpress 4.0 card. This reader is best viewed as a key component in a high-performance ecosystem, rather than a standalone upgrade. For professionals who are already investing in faster media and computers, this reader is not just a nice-to-have, it is the essential link that makes the entire workflow investment worthwhile.

I needed a new card reader because my Delkin CFExpress Reader (Thunderbolt 3) has started acting flaky on my Mac Studio. I tried a couple different cables, and it still intermittently drops the connection to the card. No bueno.
Other World Computing (also known as OWC) has recently introduced a new USB4 CFexpress 4.0 Type B card reader to complement their recently released Atlas Pro and Ultra CFexpress 4.0 Type B media storage solutions. The reader promises data transfer speeds up to 4x faster than its USB 3.2 counterparts.
If you need fast transfer speeds, then the new Angelbird Performance Card Reader is a good option. It delivers reliable transfer speeds of up to 40 Gb/s.
If you don’t pick up a card reader that supports these new speeds and have a computer with a matching interface, then you won’t benefit from these cards right now. Highly recommend investing here if you can.
It is significantly faster than conventional USB-C (10 Gb/s) card readers, especially when paired with OWC Atlas CFA 4.0 memory cards.
A photographer could plug in two CFexpress Type B card readers with an OWC ThunderBlade X12 or an Envoy Ultra SSD, achieving write speeds of over 6000 MB/s. In practice, this translates to significantly faster file backups and transfers, saving professionals valuable time on set or in the studio.
