I don t know if it s identical in function to the HUYUN adapter you listed or not

iotidiot · Answer

Thanks for the link That on is definitely cheaper so I may get it Beyond that though do you have any idea about what NVMe SSDs are compatible

_dhanos_ · Answer

Yes this one

_dhanos_ · Answer

must be Key E

_dhanos_ · Answer

Also not all NVMe drives will work and we still don t know which do and which do not work

_dhanos_ · Answer

SN520 and SN530 from WD are known to be working

iotidiot · Answer

Oh cool thanks for the info

I m quite new to this topic and I must say I m quite confused Like I explained in < 1170530310027485194> I try to setup a small size factor storage for my TPi2 < dhanos > which product do you refer to when you say this one I can t see anywhere that it is key E SSD compatible neither on the adapters or the drive of previous links Is there any doc that could help me to understand this topic

iotidiot · Answer

I m a little short on time so I ll be brief This is an example adapter https a co d 2tP5rxG

iotidiot · Answer

The actual M 2 NVMe SSD is more complex Basically not every SSD is compatible with a raspberry pi However Jeff Geerling has compiled a list of ones that are compatible See here https pipci jeffgeerling com

iotidiot · Answer

I ll have to confirm but this one should work https a co d 7LWR1rJ based on Jeff s compatibility list It s not the exact model but same brand just with more GBs

iotidiot · Answer

I ll let you know if I can get it to show up

iotidiot · Answer

Hope this helps

ncasaux_96421 · Answer

Thank you < iotidiot> What I find confusing is that it says that the adapter is mainly for WiFi cards Thank you for the list I ll have to find similar items which can be shipped to France now

iotidiot · Answer

Yeah that s actually probably true But it won t matter what the device is being used for the adapter is a passive device it just routes the pins or buses

iotidiot · Answer

Good luck on sourcing your devices As a community we probably ought to start making a list of compatible devices for the CM4 surely others will run into this too

iotidiot · Answer

And in fact I think Jeff s is an open source page So we can just add there

ncasaux_96421 · Answer

I ll spend some time to investigate all this and will let you know the results here also

ncasaux_96421 · Answer

Sorry to bother you again < iotidiot> but do you know where does this key E requirement mentioned by < dhanos > come from if there is actually one On Jeff s list this item https pipci jeffgeerling com cards m2 wd pc sn520 2230 nvme ssd html says it requires a M 2 B or B+M key slot Do you know exactly what are the requirements we have to follow

iotidiot · Answer

Great question Honestly I don t know where the key E requirement comes from The idea of using the recommended WD SN520 and SN530 is contradictory as they are both M 2 B or B+M So IDK my best guess is to go with an M key SSD and use an mini PCIe to NVMe M 2 M key adapter like this one https www aliexpress us item 3256804133569487 html srcSns=sns Copy spreadType=socialShare bizType=ProductDetail social params=21241486138 aff fcid=7793c53c8cc7425fad430ed646dad36d 1700190543316 05524 mLAhpEk tt=MG aff fsk= mLAhpEk aff platform=default sk= mLAhpEk aff trace key=7793c53c8cc7425fad430ed646dad36d 1700190543316 05524 mLAhpEk shareId=21241486138 businessType=ProductDetail platform=AE terminal id=f94b5516298b4230a291f73e5274a76e afSmartRedirect=y gatewayAdapt=glo2usa4itemAdapt
