Super impressive to watch, person clearly knows what they’re doing.

But saving $200 to then need to expend this effort seems hardly worth it, never mind that it likely voids the warranty.

Maybe if it was already a few years old it might be worth it.

I suspect the video is to show off expertise rather than advertise this as a particular service they could economically offer.

Earlier quoted context omitted.

I suspect they intentionally skipped that part because it contains "proprietary" techniques they don't want to make public.

Security though obscurity is...

... commonly referred to as a "trade secret".

This is ridiculous Apple should just include a microSD slot. Who even uses 512GB of storage on a phone? It's a stupid way to try to rip off the wealthy.

It is not ridiculous. SD slot is much slower than the built-in NAND. iPhone SSD read speeds are about 1200 MB/sec, about 500 MB/sec write. The OS is optimized to take advantage of that fast, contiguous, and reliable memory.

Just tested my iPhone 15 Pro Max. Read 1600 MB/s, write 1017 MB/s.

Sequential, 512 MB test size, 65536 test count.

I once tried to replace a screen on an iPhone, and accidentally knocked a barely visible capacitor next to the connector right off the board. When I say barely visible, I’m not exaggerating. I did try to solder it back onto the board under a microscope with my cheap reflow station, but it was absolutely futile. Which is to say, as difficult as this video looks, this is being done by a person who has done similar things many times, and you’re very unlikely to be successful at this the first time around. Tread carefully.

I would have assumed as per previous iphone models that they needed to desolder the nand and put it into jc pro or similar in order to clone it to the new nand. Interesting that they just grind the old one off and do a dfu restore. I wonder what was done for that process.

The care taken can only be described as mesmerizing. If you want proof that Apple is full of it and the whole "bootleg parts can compromise security," then here it is. Apparently, a lid close sensor is a major security risk - where NAND is not?

Let’s say you travel to a foreign country that has some level of corruption in immigration.

Your devices might have or receive information their government or just some company in the country wants.

You get detained for extra questioning. Your belongings get taken for review.

What parts could a reasonably skilled person quickly replace in less than 30 minutes that would compromise security? THOSE are the parts they’re worried about.

The threat model of someone trying to secretly grind off and replace your NAND without your knowledge is what, exactly?

So what? How is that additional bandwidth relevant to 99% of phone users? All they have is photos, and most of the photos sit on internal storage for an hour before being uploaded to iCloud. UHS-III goes to 620 MB/s that's more than enough. The OS would be fine with 100GB internal storage

Similar to the lightning cable, generates an artificial market. Making design choices against the best interests of the customer. Not sure why anyone would be Ok w that. Restricting users options, taking advantage really

Do UHS-III microSD cards actually exist?
