How to validate SMART?

Question

Hard disks

The situation is as follows: Everything slows down, checked the percentage, the operative, ran through the processes, everything is fine.
I looked at the smart status in Acronis Drive Monitor - 9%
looked at the same thing in CrystalMark, it just writes an alarm.
Looked through Powershell snippet
Writes OK.
Who to believe?
PS Snippet code:

$WMI = Get-WMIObject -Class Win32_DiskDrive
ForEach ($Drive in $WMI){
     $Drive.Caption + ": " + $Drive.Status
}
