Unclear for a laptop, but for a workstation 1tb+ is what you want for any sort data science stuff.

Yeah, good luck with that at current RAM prices though. DDR5 RDIMMs are going for $20/gb+ right now which means 1tb is $20k, and that's with fairly conservative pricing too.

I've been looking at building a high memory workstation recently but the RAM prices are just prohibitive. Best option atm for 1tb+ seems to be to go back a couple gen and buy DDR4, you can get 1tb at under $5/gb right now. But obviously you're giving up some performance in the process.
