Does LG Nexus 5X support OTG cable?

Of course, being the latest generation device with Android Marshmallow, it does have support for USB OTG. You can connect your external drives to the Google Nexus 5X and view the content on them on your phone.
Please check the file format compatibility between that on the drive and those supported by your phone. You may need to format the external drive to the required file format in case of incompatibility. Be sure to back up the content in such a scenario.

As per discussion on GSMArena, yes the LG Nexus 5X supports OTG Cable. There are however few things missing like - lack of FM and Dual SIM. However OTG Cable is supported and you can test it out by connecting the drive to the phone. As it is android device you can rest assured that if another phone with andorid on it can read the files, then surely this phone can as well.
