I've been considering building a new PC but this raised a few questions, and wondered if any of you know the answers.
I will want to use an M2. SSD Gen 4.0 to get maximum speed for booting and applications. But I have older slower M2.SSD Gen 3.0 to hold games and other stuff that I would want to also move to the new system. But I've read that if you install 2 M2 SSDs of different speeds they both get reduced to the slowest drive. If this true? Or only for certain motherboards? Some motherboards now have support for 4 M2s to be installed. But would this be the same, With the slowest of the 4 dictating speed, or are the seperated to prevent this.
I've also been reading that when more then 1 M2 is installed it slows the overall system bus down and reduces GPU performance because it takes a hit to the PCI-E bus. Is this true? That's not something I had considered or even thought about before.
I've also read that some motherboards disable SATA ports when M2s are installed.
I normally buy Asus motherboards and read that slots are routed through the chipset, so there are no impacts on your GPU PCIe lanes.. If you ran all M.2 slots at pci-e x4 bandwdith you'd lose some SATA Ports and one of the smaller pci-express slots . Hmm...
Do some motherboards have the option to select M2 slot mode?
