Ubuntu 13.04. The number of bad sectors on my SSD has steadily increased until 226 bad sectors today.

The thing is, I don't know whether 226 bad sectors is 0.0001% of the SSD, 1% of the SSD, or 99% of the SSD.

I haven't found anything on the internet this morning to answer this question.

The Disks utility doesn't tell me either, and I can't find the information in SMART Data.

sudo smartctl -a /dev/sda shows this:
