I don’t think loading two wave files into multiple tracks warrants a dual drive setup lol. Also, Pro Tools runs fine on a single hard drive for a task like this - i just tried it, have some perspective rather than spreading third party fallacies please as it’s not helpful for anyone - particularly when you’re telling others they’re being ‘ridiculous’.
The second hard drive for Pro Tools is mainly recommended for recording high track counts at once and it’s more controllable putting content on a secondary. Majority of pro-tools users that record do so with multi-mic setups (Drums etc.). That is totally different to this performance test which is CPU focused and not recording any audio whatsoever.
Large majority of people running Cubase are doing so on 2-4 input audio interfaces, i presume you using some much larger amount of inputs to class this as ‘ridiculous’?
