Optimal SSD question

[Jimmernick]

Hey I am looking to add a new ssd to my pc. My motherboard only has one m.2 slot which is already being occupied. I know they make adapters for the pcle port which allow you to add a second m.2 slot. Would this be better than me just getting a regular sata ssd for my motherboards sata port. Or will the fact that I am connecting it through an adapter slow the m.2 drive down/ cause any other issues to the point where I should just forget that idea and go for sata ssd. For reference I have the b450 tomahawk max. In short, what do i need to know about using an m.2 drive through a pcle adapter port in terms of the drawbacks.

SSD M.2 on a daughter card works well and is still very fast.

I have a PCI gen4 x 4 on my MB and dropped an M.2  on it with no issues at all.

I also have one of those tiny PCIe slots and it also has a daughter card with a Gen 3 2TB m.2 as it was so cheap I could not afford to let it pass. that also works perfectly for backups etc. Only downside was that using that slot disabled 2 x sata leaving 4 of 6 but as I have zero HDD in the system who cares was my thinking.

My PCI 4 card was around 16USD and the PCIe one a got for around 10USD Easy to do and faster than the sata drives
