Why laptops doesn't have PCIe x4 (or may be x8) interface port connector for storage drives ?

[Ethos Evoss]

Hello guys
I been wondering how SATA interface going down and how it slows down capabilities of speed in laptops..
We all know that SATA becoming lame and it slows down laptop storage disk performance.
I was wondering why desktops has this port PCIe (x4) on motherboards and laptops not ? This port is laptop size friendly it is not big so it would fit in laptop motherboards..
The laptops are limited to ancient SATA which slows down SSDs capabilities and real performance of NEW SSDs are wasted..
Please, guys if anybody is interested in this, please join and we can discuss about this topic.

Oh but some have already. Its just not that mainstream yet.

Take this for example. https://www.asus.com/Notebooks_Ultrabooks/G501JW/
And here is a list of them. http://laptopmedia.com/laptop-m-2-ngff-ssd-compatibility-list/ (well ASUS at least)

There aren't a lot of options for laptop pcie SSD's, perhaps the manufacturers don't find any reason to shift to it since currently, for the common consumer, sata III is enough for their needs. And having 2 ports just for SSD might not be so practical for a laptop. Having only 1 port (M.2) for the laptop will also limit the consumers options, and currently, the HDD and RAM are the only really upgradeable parts of a laptop.

Maybe this year, it will change cause samsung and kingston has started mass producing PCIE SSDs for laptops and seems to be going forward with it.

CES2015 introduced these

So I guess, give it some more years or so, and we will start seeing it in the mainstream market.
