Yes you can. You need to use Configurator to do it. It has been confirmed by iFixit. It’s the same as the Mac Pro was: https://support.apple.com/en-us/HT210626 . You can’t just swap a disk. You have to actually re-pair it with the crypto and then reprovision it and recovery etc.

Again Linus doesn’t know what he’s doing. Another influencer confirming my point.

This is not a PC. That’s where the assumption goes wrong.

You're making a confusion between replacing and upgrading.

He showed you CAN replace the SSD modules but only with identic size ones, but you CAN'T upgrade to bigger ones as that triggers the firmware lock.

Watch the video he posted he tried what you mentioned.

Literally nobody on YouTube, certainly not Linus, has attempted to upgrade the storage modules with a supported configuration that the machine is shipped from the factory with.

There isn't a single other SSD controller on the market that knows how to work with arbitrary quantities of NAND flash chips because it's an unnecessary engineering challenge, I don't know why anybody thinks it's remotely reasonable to expect Apple's to be different.

Yet.

Also there’s some holes in the back you can upgrade your storage with…

I always liked the LTT videos and was a subscriber. I don't think there's anything wrong with reviewing products and having a certain opinion, however Linus has a stake in a company which makes laptops whose main selling point is the ability to upgrade and repair the parts (Framework). He has a horse in the race. This doesn't automatically disqualify him from having an opinion, at the same time I don't value his opinion as much as an independent reviewer like Steve at GN.

That is troubling for me and I believe is not a super ethical practice!

Edit: Fix grammar mistake

This is cart before horse. Linus worked with PCs for years and saw (obvious) problems with Apple's hardware, and so he's invested in a solution. He's been critical of these things since long before Framework was founded.

Linus is only after clicks and subs.

That doesn't change the facts though? They don't let you upgrade the storage even if you have two first party storage cards.

It doesn’t matter regarding what I said. It’s about dissing your competitors. Sure that doesn’t make it a lie but it’s better if people know where you stand; As an independent reviewer vs shareholder of a competitor brand.

It also affects how he presents the facts and directs the videos.

I say this while loving Framework and hoping that their approach puts pressure on likes of Apple for openness. No sympathy for Apple here.
