M.2 PCIe x4 drive in Sager 8651 / Clevo 650SE

Hello!

First post, apologies if this was already answered somewhere but my searches did not find anything on this matter.
Also reposting this in relevant owners thread.

I am looking to order Sager NP8651 through XoticPC. I had several questions and wrote an e-mail to XoticPC sales address, one of the questions was regarding Samsung 951 M.2 PCI as a boot drive option. I received a reply from them, person replying to me wrote "From everything that i've seen i don't normally recommend PCIe for the 8652/8651 has it doesn't really use the benefits of more lanes still, however it does fit in there."
That's a really strange answer which is so ambiguous that I could not understand what exactly is the reason. NP8651 has M.2 Wi-Fi card but AFAIK it should not influence PCIe lanes on M.2 storage slots. Or - totally reading between the lines - is it because Samsung 951 is x4 and motherboard chipset or design does not allow it to work as x4 and forces it into x2 thus not giving any benefit over x2 drive? Samsung 951 is currently the only M.2 PCIe option in XoticPC configurator, all others are SATA.

Any ideas?

 

Not sure what they could have exactly meant by that reply, could be a few things likes combining a second m.2 card with it. You can reply to the rep to ask for clarification. They could have been thinking that the 4k speeds can be lower then standard m.2 drives. Those speeds reflect more of daily use speed.

 

Maybe this will clear it up for you.
