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。

Works flawlessly. Very fast. I'm using with CFExpress type A 4.0 cards, and an getting very close to the published speeds. Important to connect with good USB C 4 cables, otherwise the speed dropped off significantly.

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。

RED推奨cfexpressと聞いて購入。全くエラーも無く、快適に使えてます。m 2SSDに転送も100Gぐらいなら1分かかりません。大容量データーも、ストレスなく使えて助かってます。
