That's all quite well for now, but what about a year or two into the future? Look around the site for graphs of some year old cheap CMC media and see how well it holds up. Better to spend another 30% on a disc manufactured to last .
I appriciate that verbs are the way to go in terms of 100% efficiency, but friends of mine have had a lot of success with various discs, including aones, riteks, cmcs and ricohs. if they last a year or more thats a risk some are willing to take. but in terms of cost, a case of 25 verbs will set you back
