50gb cache is handled by squid just fine.
I'm not an expert, but I'm using 16 256 for a 40gb cache and I don't see
any issues. IME before changing values without a deep understanding of
the technicalities involved, it's safer to stick with the defaults.

Also, you don't specify the amount of RAM of the server nor the value of
cache_mem parameter.
