200,000 write cycles is a lot. You should have no problems with the memory stick at all. Just write to it normally. If you were to push 100 write cycles every single day, 7 days a week for 12 months, that memory stick will probably last you 5 + years. If you write less than 100 times, then it should last longer if the IC doesn't prematurely give out. That's if the 200,000 write cycles is accurate.
I seriousy doubt you'll write 100 times a day though, lol. You are just fine. By that time, new memory sticks will be even faster and better anyways.
