我刚刚设置了一台服务器，里面有10块同型号的硬盘，它们连接到华南智X99-AD3主板上（https://www.amazon.com/HELLOLAND-HUANANZHI-Motherboard-Supported-Supports/dp/B082W24TBR）。dmesg | grep SATA显示它们都处于6.0Gbps模式。

我正在用 bht 运行多个 badblocks 测试(https://github.com/ezonakiusagi/bht) 在这些驱动器上，我注意到其中四个硬盘比其他六个硬盘慢。请注意，虽然经过的时间相同，但四个磁盘的进度比其他六个磁盘少得多。

我注意到在 dmesg 输出中，四个磁盘已连接到，0000:00:11.4而其他六个磁盘已连接到0000:00:1f.2。lspci 显示以下内容：
00:11.4 SATA controller: Intel Corporation C610/X99 series chipset sSATA Controller [AHCI mode] (rev 05)
00:1f.2 SATA controller: Intel Corporation C610/X99 series chipset 6-Port SATA Controller [AHCI mode] (rev 05)
它显示一个叫做sSATA Controller，另一个叫做6-Port SATA Controller。有什么区别？我仍然想知道这四个驱动器速度慢得多的根本原因是什么？云我修复它？
以下是完整输出lspci -vvv https://pastebin.com/R4TFwGq7和lspci -tv https://pastebin.com/3w73uZK9
