SSD Any day or HD plus NVDIA dedicated GPU not shared,,,,,
:wave: In answer to your Question, yes I have used on small Routes, and no detectable problem, however I did use on I think 80 mile Route, and if I recall, It jammed up Trainz, and didn't work correctly, also it was on old HP Envy, not powerful enough in Memory or HD wise,,,,,.
Knowing what I do now, I would never use the Option again, it kind of like working with Bad Chemicals in the Yard, sometimes it is not worth, what could happen to you......:'(
So I would just make sure my Assets are in good order for dependencies and errors, erase what's not good, and delete irreparable items Etc, and sanitize the Route that way......
As for your HD to SSD , it is 10x Faster, and your computer stays a whole lot cooler with Chip Drive (SSD) over hot mechanical drive.......I did this on HP Envy, and now I have a ASUS ROG laptop with M-2 SSD and Samsung 850 EVO, 32 megs of Ram, 1050 GTI NVIDIA, and Trainz flies with my setup...Difference is day over night, raging fast.....I am one happy camper.......Resolution and FPS it great too.......Can't beat that after using integrated Video Card on HP Envy an can't change out the Intel piece of junk Video Card.......Never do that again.....:hehe:
NVIDIA all the way for me.....
If you get Samsung SSD, don't forget to use MAGICIAN Software from Samsung, it makes your SSD Scream in speed......Oh yah....!!!!
Hope this helps you,,,,,,,
