Not sure I follow, but I don't understand why the drives need to be throttled in the 1st place considering that SF claim their controllers have the best wear levelling in the industry. My take on that graph is that write activity needs to be ether below or on that life curve line - not above.

I also don't understand how throttling works. For argument/ simplicities sake is it like this?

You are allowed to write 20GB a day. The next day you write 30GB. You have exceeded your daily write allowance by 10GB. Throttling then kicks in over the next few days to make sure writes are slow enough that it is impossible generate 20GB of writes. After a few days you are back on an average of 20GB. Throttling is then turned off.

How much do you need to write for throttling to kick in? How long does the drive remain throttled? Is the extent of throttling directly correlated to amount of writes that have been exceeded?

Does a secure erase clear the throttling?
