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!
