Yes. I thought about it. I had a 512 GB HDD (10 years old) and a 1TB HDD. But i needed another HDD only for movies. So I purchased a new 2TB (E Drive).
But don't want to invest on SSD now because in future I want to buy a 1TB SSD for new computer. Which is very expensive now. So I am using my old 512 GB for C Drive which I use only for Windows, Software and Games. And D Drive 1TB for other files, video, photos etc.
I play only GTA IV, it's running smoothly, and booting time about 1 minute 15 second.
