I am building a new computer. My 10 yr old current pc 2 Seagate standard hd. All steam-origin-uplay games on 2nd hard drive, most programs on 2nd hard drive and backup and photos and music. Windows 7 on primary hd. with some windows applications. Always deleting temp files, update windows programs on primary driven, that cant put on 2nd drive. Never worry about drive wearing with limit it can read or write,
