Thanks for the reply. You have a very good system, which is good for not only editing but somewhat for gaming too. Doing some more research, I have found that things like Multicam editing indeed work well on SSD, whereas rendering on Vegas Pro makes 0 to very minor difference, no matter the source is on SSD or HDD. But keeping programs & OS on SSD is good. So I’m probably gonna go for 500GB Samsung 850 EVO to pair with Ryzen 1700 as compared to 1TB unless the rates of the 1TB fall down. Rest will be HDD storage. So as a whole, rendering, atleast on Vegas Pro is mostly CPU limited process. The answers provided here, are good to start finding. Thanks
