How can I know the average writes per day?

I used iostat (part of sysstat). Perhaps I should have checked first
if it is accurate. 8-/

If you're running ext4, you can look at:
/sys/fs/ext4/sdXX/lifetime_write_kbytes and
/sys/fs/ext4/sdXX/session_write_kbytes

smartctl show me 229h Power_On_Hours (I buy it one month ago).
And /sys/fs/ext4/sdXX/lifetime_write_kbytes show me 19940467

So:
229h = 9,54 days
19940467 kbytes / 9,54 days = 2Gb/day

I think that it is too much. I use it on my laptop only to see my e-mails (Thunderbird) and use OpenOffice.org on my work environment.

Regards and thanks for all!
