Is there a practical or performance difference between the M.2 NVME connectors on the ASRock A300 STX motherboard in the DeskMini?

I will put in one NVME drive, and will probably put it on the back of the motherboard to allow easier access in the future should I want to add a second SSD, since I don't have to remove the motherboard for the second SSD. I would use the front connector if there is a performance advantage to doing so.

Is there an architectural or performance difference between the two connectors, that would make me favor the front connector?

If I look correctly both are PCIE3x4 if you use an 3000+ Chip. The backside port seems to be connected to the CPU, so it should actually be the slightly faster one.
But in fact there won't be a difference under normal use. Even if you'd use a 2000 CPU.

Like @max31092 said, one of the M.2 PCIe slots is a x4 while the other (I think the back one?) is x2/x4 depending on the CPU you use, but yeah under normal use you won't notice a difference most likely.

I'd be a little wary of using the back slot because of thermals. You might be able to put a thermal pad on it and then it can sink heat into the backplate, but I haven't gotten around to trying that yet....
