Solid compression concatenates files to maximize the efficiency of the LZMA algorithm. Downsides:

If the archive is corrupted, it is more likely to lose all data rather than just the corrupted file. SmotherRewind.7z

A "solid" archive in 7z, such as a hypothetical SmotherRewind.7z , refers to a specific compression method where all files in the archive are treated as one single continuous data block. This creates much smaller file sizes compared to standard zip files, especially when compressing many similar files. such as a hypothetical SmotherRewind.7z

Adding or removing a single file requires rebuilding the entire archive, making it slow. making it slow.
