My internal 1 TB drive has failed after many years of sterling service. What do I replace it with? I have a 250 GB Samsung SSD as boot drive but I do need more space for games and photos. I also have a Synology with 2TB.
Do I go for another 250 GB SSD or another spinning rust drive?

Do you have any need for the 1TB drive? IE, are you currently using 250GB+?
