@Nasrul Islam, Thanks for posting in Q&A. Based on my checking, I find it can check the Total storage space, Free storage space and Total physical memory under device hardware. Here is a link with more details:

Currently, we can also add "Total storage" and "Free storage" columns under All devices, add filter to get the devices you want and export the information you want.
Hope the above information can help.
