Try if you can pack the data.

With 128bytes there are still some days missing :-)
And maybe you should give some percent plus.

In the end it is a matter of cost (your time <-> chip).
If you don't have to care for the chip price, I'd go for one
which can hold 2 times lifespan or as already suggested go for
FRAM (these are also faster).

Your supplier should have data on this. AFAIK the 100k is the minimum in
a standard enviroment (what standard you have to ask the manufacturer).
Often it is 20 degree Celsius and some x percent moisture.
