Is RAID 6 a good choice for running a computation server?
'It depends' - stock answer sorry but it depends on your disk IO needs, there's no 'one size fits all'.
What I will say is that R6/60 is a generally fine option that may well suit your needs, the only other option really being R1/10, which is faster but obviously uses more disk space, though I know a lot of people really like ZFS if that's appropriate for your setup. What you should avoid entirely is R5/50, it's essentially dead and has been for years, it's dangerous basically.
