Review: TBコントローラチップの重要性とケース品質 - これまで格安のTB4ケースを使っていましたが、耐久性を考えこちらを購入しました。 まず放熱製の高さが段違いです。 安価なケースは冷却に余裕がなく、ファン付きは騒音、不具合、耐久性の観点からマイナスの方が目立ちますがこちらは堅実で単体でもしっかり冷却しています。 特筆すべきは高負荷時の安定性、速度維持です。ベンチマーク上は高速なケースも用途によって全く速度が出ず、早いはずなのに遅いみたいなことがよくあります。 その点こちらはさすがOWCで、DTM、動画編集の長時間使用でも安定してしっかりした速度が出ています。 ベンチマーク上ではなく体感でそれが実感できます。 M.2SSDは速度よりもコントローラチップとケース性能の方が遥かに大事だと実感しました。

最高を目指した結果 行き着く先 これ以外使ってないが解らんが 困ってないし 気に入ってる ほんのり温かくなる程度の感覚

### ⭐⭐⭐⭐⭐ すごく良い！ 転送速度が早く、無音。
*by B***9 on November 9, 2025*

macbook M1に繋いでいます。サムソンの990PROを入れましたが、内臓SSDより早い3000MB・秒以上のスピードが出ており素晴らしい。本体の熱はさわれないほどではなく、ファンが無いことで無音なのが良い。ちょっとお高いですが、デザインもよく持ち歩くのにも大きすぎない。素晴らしい商品だと思います。
