Yeah, the point would be to keep the two Purple drives as they are for recording the bulk footage (I record 24/7), but set up the Seagate HDD in place of the Samsung SSD. Win 10 isn't a problem but I see there are some limitations on the demo version of BI that might, but I'm not sure, skew the results. The results of such a test aren't important enough to me to merit another BI license.If you want to experiment, just partition it. There's no issue in putting OS and data on the same drive. 99.9% of pc's have traditionally used one drive only. Unless you have recorded something you need to keep, there's no issue in wiping it and re-installing. Alternatively, use your Seagate drive.
This is a point I've addressed a couple of times but it seems to get lost in all the noise. There is ZERO doubt a SSD performs better in pretty much all regards, except maybe lifespan, than a HDD. There has never been any dissention about this point in general. It's not about the cost, none of that.However, the one thing I will guarantee is no matter how good it may or may not run, it will run better from an SSD. That's a given.
The only bone of contention is how all that adds up or doesn't in the big picture. It's easy to cite 30 seconds savings on boot up or whatever, or a couple seconds on this task or that task, but if I only boot the computer or perform the tasks once in 6 months to me this is nothing. Clearly others see it differently and or use their BI systems differently.
