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.

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?
