Fast, reliable and easy to use
I’ve been really happy with this card reader so far. It feels solid and well made, and it worked straight away without needing to install anything.The transfer speed is genuinely very fast. I use it for large RAW photo files and videos, and it moves everything much quicker than my older reader. It also stays stable during longer transfers, with no random disconnects or errors.Compatibility has been excellent with my computer and CFexpress Type B cards. It is not cheap, but considering the speed, build quality and reliability, I think it is worth the money. A very good choice for anyone who regularly transfers large files.

Blazing fast transfers.
Great product. The adapter works well for Type A and the Type B also worked fine.

Blazing Fast Speeds – A Game Changer for Workflow!
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.

抜群に速くて熱くない
以前はProGrade Digitalダブルスロットカードリーダー (PG05.5) でしたがカードが死ぬかと思う程の爆熱になるのでAngelBirdの3.2gen2のカードリーダを試したら全然発熱しないので、今度は40Gbpsのコチラも試しました。速度は3000MB/Sを超えるし、カードの温度も暖かくなる程度で非常に満足です。PGのリーダーで爆熱で心配の方はコチラがおすすめです。

De beste reader voorzien van A Adapter probleemloos je cards overzetten op je laptop, ssd, Nas enz.
Deze OWC B reader met type A card adapter is echt veel sneller dan wat ik hiervoor gebruikte! Wordt minder warm dan bijv de sony mrw g2 die je bijna niet vast meer kan houden! Dus voor CFexpress cards gebruik ik alleen deze reader nog!

Speed and works. Good cable too.
Wicked fast and worth the extra money. Hardly waiting for hundreds of GBs. If you have the Thunderbolt 4 protocol... this money is gold.
