Android TV Box with min 64 GB internal

Hi. I am using and addon that buffers legal documentaries in torrent. The problem is that these files are often 30-50 GB. I am having major issues with external hard drives, possibly that most boxes doesn’t support USB 3.0 (?).

Does anyone know about a box that carry 64 GB og internal memory? I’ve tried, but I could only find a Windows box with dual booting. I am looking to run Libreelec.

Thanks!
