Review on 🔧 MSI B450-A Pro Max ATX Motherboard for AMD Ryzen 2nd and 3rd Gen with M.2, USB 3.0, DDR4, D-Sub, DVI, HDMI, and Crossfire support by Hassim Rambli ᠌

There are six SATA ports on the motherboard. They have been given numbers. Yet, this is how they are connected within the motherboard; those who are emotionally fragile should not have any trouble understanding this concept. As a consequence of this, it was discovered that the processor contains a controller that, when an M2 disk is being installed, prevents access to the SATA 5-6 ports. As a direct consequence of this, the controller must make use of PCI-ex processor lines in order to link SATA disks. As a consequence of this, I attached two primary working disks to that SATA port (in order to gain direct access to the processor), and I left three secondary disks connected to SATA ports 1-4. The devices in the device manager's list are now organized by connection like in the screenshot. Concurrently, SATA ports 1-2 are vertical slots, whilst SATA ports 3-6 are side ones. The SATA ports on the top side are the ones that have their own dedicated controller. When it comes to other motherboards equipped with B450, there is a notation that states ports are disabled only when a drive of the SATA type is connected to M2. However, if NVME is connected, the controller continues to function normally. I am unable to verify this possibility because I do not have access to an M2 drive.
