In theory, it might last that long. Unfortunately, there are two problems.
1. Flash writes blocks, not bytes, correct? Therefore if you write 1
byte, it reduces the lifespan by the same amount as if you wrote 1
block. (Since its for logging, it'll be variable length text,
unfortunately.)
2. I'm using ext2 right now, and I should probably change that. IIRC,
ext2 has the file allocation table in one spot and isn't
flash-friendly. Each addition to a file means a write to the FAT,
right? (maybe not, I'm not exactly an expert...) If so, then the area
where the FAT is might get worn down rather quickly.
