That is still a big turn off for me then.
I dont like spending 650 EUR. on 2 harddrives to find out their performance is degrading over time and there is nothing i can do about it.
Sure, i've seen a lot of ppl with extensive testing concluding that the performance degration is around 3-5% over time and doesn't get worse then that but i'd rather wait for a solid solution.

I could have sworn i already read about vendors such as OCZ updating their FW in such a way that there is a clean-up started by the controller when the device is idling at xx percent.
