That’s part of the strategy. First, go after the small project that can’t defend itself. Use that to set a precedent that is harder for the bigger targets to overturn.
I would expect the bigger players to get themselves involved in the defense for exactly that reason.
Correct about the greens. They used to be (might still be) the ones that ran at a lower RPM
What is your use case? I ask because ESXi is free again, but it’s probably not a useful skill to learn these days. At least not as much as the competition.
Similarly, 2.5" mechanical drives only make sense for certain use cases. Otherwise I’d get SSDS or a 3.5" DAS.
The big caveat is that the BIOS must allow it, and most released versions do not.
