I am extremely impressed with the OWC Atlas USB4 CFexpress 4.0 Type B Card Reader. If you are working with high-resolution video or massive photo batches, this reader is a must-have. The 40Gb/s USB4 interface is incredibly fast. I noticed a significant reduction in offload times compared to my older USB-C readers; it truly maximizes the potential of CFexpress 4.0 cards while remaining backwards compatible with 2.0 cards. The build quality is exactly what you’d expect from OWC—solid, professional, and it stays relatively cool even during sustained high-speed transfers. I also appreciate the compact design and the included high-quality USB4 cable. It’s plug-and-play and has worked flawlessly with my Mac and PC setups. It’s an investment, but for the time it saves in post-production, it’s worth every penny.

SONYαユーザーですがCFexpress TypeA to B変換カードが付いてるので購入しました。問題無くCFexpress TypeAカード使えてます、注意点としては変換カードにはType Aカードを裏返して挿入して下さいね、間違って表で挿入してはいけません。0.7mThunderbolt4ケーブルも付いてきてお得ですね、おすすめ。
