47 bios in one system.

[Whispering Dave]

Don't know if this is the highest number of bios found in one system. Probably not but it took freaking ages to find them all.
System - Stuemeae HD-Z d1-6141

That's a lot, not the record, but a lot. You may be the first person to actually bother sampling that many on one system though!

 

[Codger]

You actually found all of them? I'm impressed.

Is there anything you get from sampling beyond rank, credits and codex confirmation?

You don't need to sample to get codex confirmation, the discovery scanner on your ship or SRV can do that, so only rank and credits.
