Just thought of a concern on the MacBook Air. Flash drives / SSDs have limited read and write capacity, right?

How do I know when I am reaching that? I don't want my data to be corrupted.

Thanks in advance.

From what I understand you don't need to worry about that. Those limits are just as indication and you won't be reaching those in years (at least with newer SSDs). If I remember right, my Crucial M4's lifespan is over 5 years under heavy daily use (like 40gb write per day).

Keep regular backups and don't worry about it.
