jffs2 flash life calculation

We are developing a product, which requires a flash life span of 10 years.
Specs are - 350KB data / 10 minutes, at any given time 2MB data in flash,
NOR flash which has 100K erase cycles/ block, with 128k sector size. This is
Intel startaflash, with JFFS2 over MTD.

How do I calculate the required flash size, taking wear-leveling of JFFS2
into account. Where can I find this information?
