Would a Z690 motherboard be better equipped to run 24/7 vs a B660 because of having better capacitors? Or would both be about the same? I will be running this in a surveillance system I have that has been running for 6 years straight, and want to upgrade.
 
1- SSD, either M.2 or 2.5. Only 1.
All the rest will be SATA.
2.5" is still SATA, what motherboard you pick will determine how many drives you can have in your machine. If the M.2 drive is connected to the chipset then one SATA port will normally be disabled. The first M.2 slot on the board will be wired directly to the CPU utilising 4 of the available 20 CPU lanes. Therefore it doesn't use any chipset lanes. That's the best place for your OS drive and will let you use all the SATA ports.
 

That's a nice board, if you are fine with the 4 sata ports, for HDD. For a budget B660, this would be my pick.

3 M.2 slots........PCIe 4.0..........ATX.

Do you need any of that?

Any current gen board will be Gen 4 PCI-E, or better.

So, get an M.2 and place it in the first M.2 slot. Or, go with a Z690 board which I won't run into that problem. I guess I'll just look at the options. Thanks.

With this B660 Tomahawk you get 6 x SATA ports. You have 3 M.2 slots, 1 is wired to the CPU and the other 2 are wired to the chipset. According to the manual you can use the 1rst and 2nd M.2 slots without impacting the 6 SATA ports, it's only when you populate M2_3 that you lose access to port 7.

The Z690 Tomahawk seems to let you use all 4 M.2 slots all 6 SATA ports at the same time but obviously costs more.
