Now, thanks to your help, I have a 250GB SDD and a 1TB HDD for my new PC build. As far as read-write speed goes how should I use this space? I want to put Windows 10 on the SDD, but should I also install my programs on the SDD, or should I put the programs on the HDD and use the SDD for all the preferences and data other than saved files? Or, does that split them too much? I want to keep all my saved files on the HDD as a best practise, because if the Windows drive ever fails all your data is on the other drive.
