プチフリーズ対応<\/a>でいろいろやっているうちに気がついたのですが，USB-AとUSB-Cのコネクタを持ったケーブルを複数もっていますが，いずれもUSB 2.0のスピードしか出ないものなのです．<\/p>\n\n\n\n

USB-Cの端子をもつ外付けSSDドライブをMac miniから他のMacに内容を移すために利用していますが，Carbon Copy Cloner<\/a>でコピーを開始しようとすると，このドライブはスピードが著しく低速でコピー用に推奨しないようなメッセージが出ます．<\/p>\n\n\n\n

ちょっと調べたら解ることですが，USB-3.x対応品は “Super Speed” で5Gbpsまたは10Gbps対応なのですが，どうも手持ちにはそうしたものはないようです．<\/p>\n\n\n

写真のケーブルはUSB 3.x対応のつもりで買ったのですが，よく見れば箱の横に “HIGH SPEED” って明記してあります😓 前述のように “Super Speed”でないとNGです．<\/p>\n\n\n\n

ということで，某大手通販サイトで10Gbps対応のものであることを確認して3本注文しました．これまでのはそれこそスマホの充電用に使います．<\/p>\n","protected":false},"excerpt":{"rendered":"
