The Sabrent Rocket 1TB, a reasonable, fast $130 SSD, has an endurance rating of 1665 TBW. To have hit that rating, you'd have to have written 760 GB to it every day over those six years. At 5%, that's still 38 GB a day, every day. If you were spending more to get better endurance, you could have just bought the 2TB version, which would have guaranteed 1422 GB/day. (NB: SSDs suffer write amplification, so if you actually need 1.4TB of writes per day you should choose an enterprise drive instead.) Endurance isn't a problem with SSDs for consumers, at all. Even QLC, which has significantly worse endurance than TLC, has plenty.

I'm not aware about the TBW rating of the Mac's SSD. I didn't drill into its SMART stats. Maybe I should do that. Home workstation's home is on a Samsung 860 Pro, 256GB version, which has 300TBW. I have a slower storage tier on that computer for big files and archives so, it's only hammered when I really need that speed. When I bought the Mac, 1TB SSD was top of the line. 2TB was not available for Mid 2014 Macs. Actually, I upgraded everything as apple could while buying it I'm aware of the dynamics of SSD writes and TBW values. I personally don't write that brutally. Things get hot if I'm processing images or working on my software and need to see some detailed logs or interim results along the way. If I was using my computer as an ordinary user, I'd not worry about it at all. My family's computer runs on much simpler drives and their write volume is nowhere near me.
