I’ve got a Supermicro X11SSV motherboard with an mPCIE slot, and I’ve got a Lenovo Chromebook motherboard with an M.2 wifi card slot. Ideally I’d like to add 2 more sata ports to the Supermicro board, and I’d like to use a aliexpress M.2 to RJ45 adapter on the Chromebook. The problem is I can’t find consistent information on the speeds of these ports. It doesn’t say in either of the manuals, and from googling it seems that m.2 slots sometimes do PCIE x1 and sometimes USB 2.0, and that mPCIE is just another name for mSATA.
Does anyone have any info on how to determine what kind of speeds the ports do? Or how to determine it on a case by case basis? Thanks.
I work in IT and when I want to find out what something has, I literally pull up the manual page for the motherboard. It tells you what it is. Sometimes a specifications page for a part is good enough. LLMs like perplexity can get you search results where you can then read for yourself what the actual thing does…
Supermicro X11SSV is probably not a motherboard, I see X11SSV-Q, X11SSV-Q-O, and other variants
The lenovo chromebook should have a specific model too. Search for that.
