A few years ago it was almost recommended to have a separate partition for games, a separate one for programs leaving the OS on a single partition of it's own.
Now with the advent of SSD and such, is it really worth it any more?
I personally separate games, documents and programs but I'm starting to think it isn't really worth it any more.
The person who explained it to me said if your Windows system got infected with a virus or you messed it up, then you could wipe the partition and re-install without losing games or documents. However in the six or seven years I have had this set up, I have needed that "protection" zero times. But then I am not someone who has any sort of RAID protection, I simply back up once a year to DVDs and an external HDD whenever I make major changes to a document or music collection.
It may have made sense if you had three or four different drives as to spread the load, thus saving work on the one hard drive. However I only have two so the work is still pressured on either of them.
