Panasonic and Toshiba both owe me 99,998 writes on each of the DVD RAMS that have ceased to work. Neither are scratched or marked. yet both have gone belly up and when they were working they were rediculously slow to register and write to. So I bought a few TDK scratchproofs and hey presto all is ok and im on my 3rd scrub and write. So already they have out performed RAM in terms of resilience! What is the benefit of RAM?
