Review on 💪 Mega Performance with MSI B450-A Pro Max AM4 ATX AMD B450 Motherboard by Amrit Barla ᠌

The motherboard has 6 SATA ports. They are numbered. But here's how they are connected inside the motherboard - to understand this is not a problem for the weak in spirit. As a result, it turned out that there is a controller on the processor that blocks SATA 5-6 ports when installing an M2 drive. It follows from this that the controller uses PCI-ex processor lines to connect SATA drives. As a result, I connected 2 main working disks there (for direct access to the processor), and left 3 auxiliary disks on SATA 1-4. Devices by connection in the device manager now look like in the screenshot. At the same time, SATA 1-2 ports are vertical slots, and SATA 3-6 are side ones. The top side SATA ports are those with a dedicated controller. For other motherboards with B450, there is a remark that ports are disabled only when a SATA type drive is connected to M2, and if NVME is connected, then the controller remains operational. Since I don't have an M2 drive, I can't check this probability.
