6PB Written - and still going!

So - an amazing 6PB written so far, which is 40x the SSD's rated endurance of 150TBW - and it is still going strong. 3111 sectors have failed during erasure and have been reallocated, which is 53% of the pool - 47% remaining, so still a fair bit of life in the disk. We have also just completed a 9-day power-off to check for basic data retention, and everything was fine.

Wear-levelling count is getting towards its limit - only 7% life left - so it will be interesting to see what effect that has when it reaches 0, which can't be far off now.

Finally, in response to comments on an earlier post, I have added a md5 check to ensure that there is no unreported data corruption occurring. This will run every 100 writes to the disk, and verify that the data really does read back correctly.
