MDT is a free, supported download from Microsoft that adds approximately 280 enhancements to Windows operating system deployment with SCCM. The following information for your reference:
1, MDT once installed, can be integrated with SCCM to provide more rich features related to operating system deployment. One of the main reasons we wanted to integrated MDT is its rules engine which can be configured through customsettings.ini to generate lots of inbuilt MDT variables. This is not only limited to inbuilt variable but also provides a huge scope of creating your own variables.
Once you create a TS in ConfigMgr using the MDT integration, the bulk of the scripts used by MDT stand-alone are also used in the TS. It's these scripts that provide access to the MDT DB as well as MDT variables which are accessible to the ConfigMgr task sequence as task sequence variables.
2, MDT is suitable for small-scale environments, while SCCM is more suitable for large-scale environments. If you are in a very big organization, then Microsoft recommends a combination of MDT and SCCM. More specifically, if you have thousands of computers and many different applications to manage it’s a good direction to consider.
Here’s how it works. You build and test your images using MDT standalone. Then you can deploy the images to a small number of pilot/test users with Windows Deployment Services (WDS), a network-based Windows installation technology from Microsoft for doing LTI deploys using PXE. (Like MDT, WDS is free.) Then once it’s all confirmed to be golden, you can do mass rollouts with SCCM.
