Raid
為什麼一個驅動器以 3.0gb/s 的速度執行？
我有一台伺服器，我將很快更新 Adaptec RAID 控制器韌體和驅動程序，所以我在 arcconf 中檢查了一些事情。
這四個磁碟都是相同的型號，配置為 RAID10 卷。在執行 arcconf 的 GETCONFIG 時，我有點驚訝地發現其中一個驅動器以 3.0gb/s 而不是 6gb/s 執行，就像其他驅動器一樣。
這可能是什麼原因，有沒有辦法讓它以 6gb/s 的速度執行？

很可能 ATA (DATA) 電纜已損壞，其最大吞吐量為 3 GB/s。嘗試更換電纜，或者如果是熱插拔，請使用不同的插槽。此外，它對 5.4k RPM 驅動器沒有任何影響，您仍然可以獲得不錯的性能，因此它幾乎不會對您的性能產生任何影響。
