我有一台服务器，我将很快在其上更新 Adaptec RAID 控制器固件和驱动程序，因此我使用 arcconf 检查了一些内容。
这四个磁盘都是配置为 RAID10 卷的同一型号。在运行 arcconf 的 GETCONFIG 时，我有点惊讶地发现其中一个驱动器的运行速度为 3.0gb/s，而不是像其他驱动器那样为 6。
这可能是什么原因造成的？有没有办法让它以 6gb/s 的速度运行？

答案1
最有可能的是 ATA（数据）电缆损坏，其最大吞吐量为 3 GB/s。尝试更换电缆，或者如果是热插拔，请使用不同的插槽。此外，它不会对 5.4k RPM 驱动器造成任何影响，您仍将获得不错的性能，因此它几乎不会对您的性能造成任何影响。
