swap trick

well, i just got the sega saturn i won in a bid, and its a frigging model 1 with 20 pins for the CD cable... so, i have to stoop down and go with the swapping trick
i was just wondering how long a sega saturn would last if say i played a few game 8 hours a day by doing the swapping trick.... thx in advance
it would last just as long as it would if you played the thing for eight hours a day using an original. swapping doesn't hurt the thing if you do it carefully and gently.
