1台のドライブが3.0GB /秒で実行されているのはなぜですか？
私はAdaptecRAIDコントローラーのファームウェアとドライバーをまもなく更新するサーバーを持っているので、arcconfでいくつかのことを確認しました。
4つのディスクはすべて、RAID10ボリュームとして構成された同じモデルです。 arcconfのGETCONFIGを実行しているときに、ドライブの1つが他のドライブのように6ではなく3.0gb/sで実行されていることに少し驚いていました。
これの理由は何である可能性があり、6GB /秒で実行する方法はありますか？

おそらくATA（DATA）ケーブルが損傷しており、その最大スループットは3GB /秒です。ケーブルを変更するか、ホットスワップの場合は別のスロットを使用してください。さらに、5.4k RPMドライブに違いはなく、それでもまともなパフォーマンスが得られるため、パフォーマンスに実質的な違いはありません。
