这是 feature
NOTE The Disk counter has been removed from the Performance tab in Windows Server 2012. This is because there is significant performance impact to collect Disk metrics on a Server due to the overhead Task Manager may cause in querying each Disk IO for each process/thread on individual disk. |

@vibbow 感谢，顺藤摸瓜查到了怎么开启：
prints: Both Logical and Physical Disk Performance counters on this system are automatically enabled on demand. For legacy applications using IOCTL_DISK_PERFORMANCE to retrieve raw counters, you can use -Y or -N to forcibly enable or disable. No restart is required. – David Balažic CommentedFeb 1, 2023 at 9:56 |

这个有些年头了，微软当年的说法是加上之后性能会有问题。所以一直都是在性能监视器里面查看。但是那个地方有个坑爹的之处就是读写速度是个平均值，没有瞬时值。
