The NAS reports TiB (1024*1024*1024*1024 bytes per TiB), drive manufacturers use TB (1000*1000*1000*1000 bytes per TB).
5 TB is the same as 4.55 TiB. (The NAS is taking about 4 GB for the OS and swap, but that is in the third decimal place when you scale up to TB.)
With 4x5 TB you'd have a 15 TB volume. That is the same as 13.6 TiB - the formula is 15*(1000/1024)*(1000/1024)*(1000/1024)*(1000/1024)
