Looking for sample javascript (not vbscript) to access WMI Objects

  You'll be after "Win32_PerfFormattedData_EmdCache_ReadyBoostCache.TotalreadbytesPersec". But you won't be able to read this without Elevated Admin rights, so it's going to be pretty useless!
  
  Here's the code:
  
  var oWMI = GetObject("winmgmts:{impersonationLevel=impersonate}!//./root/cimv2");
  var cItems = oWMI.ExecQuery("Select * from Win32_PerfFormattedData_EmdCache_ReadyBoostCache");
  
  var cItem = new Enumerator(cItems);
  for (; !cItem.atEnd(); cItem.moveNext())
  {
  var cacheSize = cItem.item().Bytescached;
  var totalReadBytesPerSec = cItem.item().TotalreadbytesPersec;
  }
