GA-Z270X-Gaming 5 and m.2 SSD

Hello.
I saw a lot of topics but did not find an answer to my questions.
So.
Is it normal that in the BIOS in a special section of the NVMe I do not see my SSD?
The claimed speed that shows my Plextor M8Pe is simply awful.
It is far from the one I saw in the reviews and specifications of the manufacturer.

M8Pe / (G) variants

These are the supported drives:

M2PN13 Plextor PCIE Gen3x4 2280 PCIe M M8Pe PX-128M8PeG-128GB 2280 Gen3 x4 (2A) 128GB
M2PN11 Plextor PCIE Gen3x4 2280 PCIe M M8Pe PX-1TM8PeG-1TB 2280 Gen3 x4 (3.5A) 1TB
M2PN12 Plextor PCIE Gen3x4 2280 PCIe M M8Pe PX-512M8PeG-512GB 2280 Gen3 x4 (2.5A) 512GB

The read / write speeds vary depending on the size / model.  What speeds are you expecting? What speeds are you seeing and what are you using to benchmark?

How was windows installed?  Did you install to the device using UEFI prefixed OS heading?
