For a one off home 'burner' you should be ok although I have a thing about waste.
To put in context (heat & manufacturer detail excluded) then the spreadsheet says that 4KB/s with one write every second might give you 6 years on a consumer 8GB using basic FAT. Most commercial cards will not quote write cycles (& for good reason) but will say something like '5 years with normal use' wtf that means. Well 4KB/s is more than most normal use IMHO so I figure you won't get 6 years on commercial - the card cannot be achieving even 300 per sector. Check my figures, easy to loose a 0
The cheapest card with promised write life (3000) will cost you around $30 for 8GB. That gives you 60 years write endurance @4KB/s but promised, you can sue them after 50 years!
Also remember that writing frequently exposes you to power fail issues. FAT is not your friend. Perhaps you remember having to properly shut down your PC to avoid corruption. Try an embedded FLASH FAT system if feeling nostalgic
This is not an ESP issue, it is the very nature of FAT.
EDIT: So maybe raw might be better for you. You can recover from power fail corruption but would loose data, dual partitions and buffering aside.
