[QUOTE=Stereodude;2701963]I get the repeatability aspect, but how can you know if the data is valid and that you’re not getting false error spikes or values? Unless you’ve got the real deal expensive disc analyzing system(s) and use that as a benchmark, how do you know if the drive your testing is accurate or not? You don’t… However, if you’re doing a comparative analysis you don’t necessarily have to know if your ruler or measuring device is absolutely accurate or not because it’s a relative mark. In that case it doesn’t really matter what you use.[/QUOTE]
There are CATS vs consumer drives comparations already, and false spikes/errors reported can be sometimes tested with a other drives and TRT: if there is are a lot of errors (and getting for example a 0 QS) but the TRT if perfect and when scanning with all other drives they show a perfect (97 QS for example) disc then you may start to doubt the reliability of that drive. Still, everyone has their own opinion, that’s why I created this topic. Let me ask it differently: which drive would you use and mostly trust when you want to scan DVD media, if you would have the possibility to use any consumer one?
