That being said, though, it shouldn't be necessary to avoid using a
journal on the Intel SSD. Intel says that laptop will last at least 5
years with 10GB worth of writes per day, and that's a huge amount. I
have an X25-M SSD in my laptop, using an ext4 file system and with the
journal enabled, and since the file system was created 266 days ago,
when I put my X25-M into service, the drive has seen 570GB worth of
writes, so I'm averaging 2.14 GB writes per day.
That really depends on the software you use. Just fetching mail on my
machine causes about 500 MB of data written to disk. That's because
I'm using Gnus with nnml and slightly large mail folders and Gnus
rewrites those index files from scratch each time new mail for a
folder arrives. I should really consider this a bug and fix it, but I
haven't yet found a good solution.
So sorry for this stupid question, but...
How can I know the average writes per day?
I try run smart, but it not help me:
