This looks like an M.2 SATA SSD to PCIe 2.0 x2 Adapter. So it has a built-in SATA controller chip? Does it support booting from connected SSDs?

Yes, there is a SATA controller chip on this card and yes it does support booting from a M.2 (not Msata), and NOT M.w NVMe (which is the new very fast storage interface). It will boot M.2 AHCI.

I have pci-e 1x slots, will this adapter fit on those?

Yes, that is what it says in the description. Just be aware that the M.2 slots are SATA, so you cannot use an NVME (i.e. PCIEx4) SSD in this adapter, but only SATA SSDs.

Is this raid, or just dual drive? 2 port m.2 ssd to pci-e x1 adapter b or b+m key (si-pex40115)

No this is not a raid controller. This is a pci-e adapter for m. 2 ssd. You can set this up for a daily backup in windows if you want.
