I use OSFMount for a RAMdisk (fastest R/W RAMdisk); understand though that the majority of RAMdisks are NOT dynamically sized so you can run out of space decompressing large files if your RAMdisk is smaller than the expanded file (hence why my RAMdisk is 16GB). Modern NVMe, due to many factors involved with decompressing/writing a file, will give you similar performance (there is certain overhead that limits the performance of decompression/writing files).
