I have an external USB HDD that mostly contains MP4 videos, about 100 MB to 2 GB each. To store and retrieve those more efficiently, I formatted the drive with a rather large cluster size – 4 MiB if I remember correctly. Since every cluster can be occupied by a single file only, this would waste a lot of space for smaller files like plain text documents (including playlists), images, music tracks and audiobook chapters.
However, I want to put part of my audio collection onto this drive without reformatting nor partitioning it and without too much wastage. Therefore, Iʼm considering to put each album either into an (uncompressed) ZIP archive or into a single MP4 container with chapter marks. Whatʼs better supported by playback and managing apps, in particular on Smart TVs? Is there a better alternative Iʼm not seeing yet?
