do m2 splitters exist?

I need it for the laptop, so I can't use those pcie converter cards
 
No, it's not possible to do that, even if bifurcation was supported, it would also be impossible to fit inside a laptop.
 
the fit would be possible with a double sided slot or a custom pcb...
None are existent, plus thermals are a pain in the neck on mobiles, unless if you have a desktop replacement/gaming/super computer, workstation laptop.

Not a thin notebook...

Your only option is usb/thunderbolt/lightning....

Good luck with your search on webcrawler...

As pointed out above, thermals would be an issue to start with.
Then you have the issue with power, as if you split a single M.2 slot into two, each slot would get half the power, which isn't likely to work well.
So yes, in theory it might work, but there are too many real world limitation in the way for this to actually work.

about that, doesn't exist some sort of board/case that allows 4 external satas with a single cable for boh communication with the notebook and a single power input for the power?

Because having a dongle for each drive it becomes quite a mess

You can get a DAS (Direct Attached Storage), which can hold multiple internal drives.
Maybe something like this?

What you want doesn't exist. It will not exist because there is no market for it in mobile devices. (Laptops, notebooks, etc)

Just use an external.

there are things like those
my main question is if there a psu with multiple sata power slots;
then with the sata/usb adapter I think that I can use an usb hub to put all of those usb to a single one

or I could do some sort of nas with a raspberry, but it's either more expensive, and I don't really need a nas

Yeah, a desktop PSU that has actual SATA power connectors

You need a harem of external drives, but you don't need a NAS? Then why do you need a multitude of storage drives?
A DAS would do just what you wanted with one power cable in driving multiple drives and one data cable out for the computer, a NAS could also work depending on how important performance is but with a network cable instead.
Or just a harddrive dock if you want that, something with 2-4 slots if you are swapping drives often.

if a larger array of storage is needed for whatever your now doing, it seems like its easier to just get a desktop. Since a laptop won't be all that portable if you have to lug around a DAS/NAS/Dock/entanglement of external drives.

I switched from a desktop to a laptop
but I still need all of those drivers

though I could have taken a cheap tablet and access to the pc as a vps/rd but I already sold the desktop...

das/nas are more expensive
I was looking now for some sort of 12v dc power+sata splitter or a small psu with either sata splitter or something like that

I've found something like that on aliexpress but it has only 3 satas and it has a weird T shaped format

Get a multidrive dock and call it good. You're making this so much harder than it needs to be because you want to be cheap and use parts that are probably going to burn up along with your drives. What you're looking for has been on the market for years.
 
Are you trying to get more SSD space for lower $$.

each slot would get half the power, which isn't likely to work well.
That's not how it works at all. One of two things would happen:
-If the slot has no power protection circuitry, which is probable as it's not designed to fit any arbitrary device but rather a single M.2 device conforming to that standard... each would draw their required power, and you'd get double the power draw (only potentially, as they're each going to use what they need moment to moment, not their max continuously). Probably it would work (electrically speaking), but the motherboard/chipset/cpu all need pcie bifurcation support for the mobo to recognise more than one device on the slot which is, to put it mildly, *unlikely* on a notebook. Most of the time you need at least a workstation board if not a server board to find bifurcation support enabled. Worst case result (though unlikely) is a fire if the power draw is far enough beyond what the slot is designed for.
-The other option, if the m.2 slot has power protection circuitry, and two m.2 draw enough to trip it, is either the slot, or the motherboard itself shuts down.
Yeah no. Middle card is NVME and SATA only. PSU you listed is a fire hazard cheapo and first picture ain't gonna fit in a laptop.
What toothless said. The pcie to m.2 adapter card has one slot wired to the pcie bus, and one slot wired to a sata header. It's just a dumb pin-adapter, not a pcie bifurcation device. Connecting that chained mess to an m.2 slot would result in having one *probably* working m.2 slot still, just on a pcie card unsecured in a pcie slot on an unsecured pcb flopping out of a notebook.

Multiplexing doesnt work unless if the chipset supports it.
 
@m4gicfour uhm, AMD supports bifurcation on all its desktop CPUs, no need for workstation stuff any more. Not sure about their notebook CPUs. Intel supports it on most as well.

And the power example was an over simplification, simply to say that the notebook isn't designed to deliver power to two such devices. The OP doesn't seem to be overly technical.

Just get yourself a dock or two

Or a four slot https://www.amazon.com/StarTech-com-4-Bay-Drive-Docking-Station/dp/B01ANR4VKE

I have no idea of they are good or not, mostly linked as an example, i got another random brand of the two slot model that I use to access drives while I work.

if I were to buy a EXP GDC or a usb/pcie adapter + a pcie/sata adapter would work (with a laptop)?

I already have an atx a psu, then for the case I can do it
