Behold! The era of USB4 has arrived with OWC Ultra-fast Compact USB4 CFexpress 4.0 Type B Card Reader. OWC has unveiled the Atlas USB4 CFexpress Type B memory card reader at the CP+ Camera & Photo Imaging Show in Yokohama, Japan, offering a transformative experience with transfer speeds over 4x faster than conventional USB 3.2 readers.
Compatible with CFexpress 4.0 and 2.0 Type B cards, it achieves real-world speeds of over 3300 MB/s, significantly reducing transfer times for large files. Designed for professionals, it features a compact, travel-friendly design with a sturdy aluminum enclosure and a new heat sink to prevent thermal throttling.
The reader supports USB4, USB 3, Thunderbolt 4 and 3, and works with Mac, Windows, Linux, iPads, iPhones, and Chromebooks. It integrates with OWC’s Innergize software for card health checks and performance optimization.
This little big guy is not just fast, by the way. It is aesthetically pleasing too. Save for the black cover, this gadget looks pretty much like a shrunken-down Mac mini.
Available for pre-order at US$99.99, shipping in early March. Meanwhile, you can learn more about this “The Flash” of the memory card world HERE.
