I was reading a while back that some new RD technology's are being tested and could be in use soon. Sorry, I couldn't find the thread to reference or if I remembered the topic correctly.
Anyway, I was wondering if it made sense to buy a top three RD now or wait until that soon to be RD technology is in place. I understand some protection is better then none, but I don't have the resources to buy new RD frequently. Also, say you buy something now, are the current RD offering capable of being upgraded to address the new threats via a flash update or would it mean a tear and replace, hence making sense to get extended warranty.
Your input is appreciated.
