I do not know really :) But scterc is officially supported by intel's 
spec, probably they did this for something.

I had some issues with timeouts for different sandforce ssds but the 
reason is unknown for me. Sandforce 2200 does not support scterc (at 
least with smartmontools), sandforce 1200's behavior is odd:
