250GB storage is nothing that can considered big nowadays. Especially if it is 15 yr old HDD model. Get some at least 1 TB HDD for such archives. This drive for example. Configure windows power management to turn HDD off after 15 minutes. Then drive will stay dormant as well until it will be really required. Used 1 TB HDD in such mode for a decade. That drive still works as archive media.Already have an ssd, i need a big storage unit only to storage games and projects on it
