VB.net监视固态硬盘F盘写入速率百分比

您可以使用 `System.IO.FileSystemWatcher` 类监视固态硬盘 F 盘的写入操作，并结合 `PerformanceCounter` 类获取硬盘的读写速率，然后计算写入速率的百分比。

以下是示例代码：

Dim fsw As New System.IO.FileSystemWatcher()
fsw.Path = "F:\" ' 监视 F 盘
fsw.NotifyFilter = System.IO.NotifyFilters.FileName Or System.IO.NotifyFilters.LastWrite
fsw.Filter = "*.*" ' 监视所有文件
fsw.EnableRaisingEvents = True

Dim pc As New PerformanceCounter("PhysicalDisk", "Disk Write Bytes/sec", "_Total") ' 获取硬盘写入速率计数器

Private Sub OnChanged(sender As Object, e As FileSystemEventArgs)
    Dim writeBytesPerSec As Single = pc.NextValue() ' 获取当前硬盘写入速率
    Dim totalBytes As Single = e.FullPath.Length ' 假设每次写入操作的大小为文件路径的长度
    Dim writePercentage As Single = writeBytesPerSec / totalBytes * 100 ' 计算写入速率百分比
    Console.WriteLine("Write percentage: " & writePercentage & "%")
End Sub

AddHandler fsw.Changed, AddressOf OnChanged

注意：这里假设每次写入操作的大小为文件路径的长度，实际情况可能更为复杂，您需要根据实际情况进行调整。
