Disk and Device Read/Write (I/O) Statistics This is an example of getting and displaying Read/Write Activity for all Disks and Device I/O. The actual UDF function _NTQuerySysPerfInfo() returns a whole lot more Performance Information for the computer; however, we are focused on I/O activitiy here. This was written as a faster alternative to WMI, as well as an alternative to >Performance Counters (see my >Physical Disk Read/Write activity example). Update 2013-07-06: Changed: Renamed module Changed: _AddCommas now uses a nicer PCRE Fixed - Copy and paste errors Added - Comma se
