Wow--the largest-NPLB-prime record broken twice in less than a day! :shock: Congratulations on the big prime. :smile:

Carlos' 331*2^600339-1 is actually the biggest found by NPLB, although it wasn't from one of the main drives.

Regardless, a nice run of bigger primes here and it's nice to see the 3rd drive finally find a new one.
