I can see your point! The trade off is having lighter ports which would stick out like a sore thumb; if in doubt, the torch on a phone is super handy! Again, I do see where you're coming from and you make a valid point
So, wait. Do all three M.2 ports (if populated with NVMe drives) disable SATA ports or does M2_2 only disable SATA ports if its populated with a SATA drive?
The article is contradictory: "one M.2 shares bandwidth only when a SATA based drive is installed with one SATA port, so even if a user is using a PCIe 3.0 x4 capable drive in the slot, two associated SATA ports will be disabled regardless. The configuration is as follows:"
If slot M.2_2 is using a PCIe drive, it doesn't disable the associated SATA port, only when a SATA drive is installed. The other M.2 ports will disable the shared SATA ports regardless of what's installed in them.
"*M2_1, SATA3_0 and SATA3_1 share lanes. If either one of them is in use, the others will be disabled. If M2_2 is occupied by a SATA-type M.2 device, SATA3_3 will be disabled. M2_3, SATA3_4 and SATA3_5 share lanes. If either one of them is in use, the others will be disabled."
M.2_2 allows use of a PCIe SSD without disabling any SATA ports. I don't have the Z390 HSIO layout to hand (in pub currently), but all three of the M.2 slots on this board can use SATA drives at the cost of give SATA ports.
I really wish we could get some in site to the sub components of motherboards. Things like, what's the performance of the m.2 slots when all 3 are configured? How about usb transfer speed tests. Some sound testing? Wi-fi tests. Any issues with dual nic's and teaming?

I'm not a big fan of dark color connectors on motherboards. Its a pain when trying to connect them if in tight spot.gavbon - Thursday, November 1, 2018 - link

Assuming the same HSIO layout as Z370:The first m2 can block between 0 and 2 SATA ports depending on how other IO lanes are configured.
The second M2 will block 2 SATA ports.
The third M2 slot can't do SATA, and won't block any sata drives.

The official specifications state:"*M2_1, SATA3_0 and SATA3_1 share lanes. If either one of them is in use, the others will be disabled.
If M2_2 is occupied by a SATA-type M.2 device, SATA3_3 will be disabled.
M2_3, SATA3_4 and SATA3_5 share lanes. If either one of them is in use, the others will be disabled."
M.2_2 allows use of a PCIe SSD without disabling any SATA ports. I don't have the Z390 HSIO layout to hand (in pub currently), but all three of the M.2 slots on this board can use SATA drives at the cost of give SATA ports.

Okay, cool. That was my reading from other research, but the article wasn't clear.Dug - Thursday, November 1, 2018 - link

It's either Ashes of The Singularity and AoTS, or Ashes of the Singularity and AotS.Don't mix the two.
