A friend has been switching all his computers to solid state drives, and he says it makes a tremendous difference. Case in point -- he uses the freeware (open source) Libre Office suite. I have that on my computer, and I regularly kvetch about how long it takes for the splash screen to load, display, and go away before the actual program shows up. He has always said he doesn't find the wait nearly as interminable as I claim.
A few days ago he started up Libre Office on a laptop that doesn't have a solid state drive yet. He e-mailed me specifically to apologize. 'Now I know what you were talking about." I think it's worth a try ... except that I don't think it's worth buying Windows 10 for it. Maybe some flavor of Linux?
