You can skip compression while still including files by setting the compression level to 0 (store).

7z allows for non-solid mode, which is beneficial when specific files within a large archive need to be accessed quickly, as it reduces the need to decompress the entire archive. K42.7z

7z can be used to archive the contents of block devices, such as /dev/sda1 , by piping data from cat or similar commands. Typical Scenarios You can skip compression while still including files

Using algorithms like LZ4 is recommended for data that is already compressed, as it prevents inefficient re-compression and speeds up the process, achieving high compression/decompression speeds. Typical Scenarios Using algorithms like LZ4 is recommended

For large file sets, 7z provides multi-core compression, making it faster than many single-threaded alternatives. More details on using 7z with block devices ?
