Maybe Apple iPhone 16 Pro 1TB uses slow QLC flash technology

Thanks to netizen Wu Yanzu from South China for submitting the clue! According to reports on January 17, in order to reduce costs, the iPhone 16 Pro series models equipped with 1TB storage may use QLC NAND flash memory with slower read and write speeds.

Noted that Apple currently uses more expensive TLC NAND flash memory on the iPhone. The advantage of QLC flash memory is that it can cram more storage into a smaller space and is cheaper, but the disadvantage is that it has slower read and write speeds and is less durable and reliable than TLC flash memory. Of course, Apple can mitigate these issues through specific optimizations. The report also said that the use of QLC flash memory may make it possible to launch an iPhone with 2TB storage for the first time. The current maximum storage capacity of the iPhone 15 Pro Max is 1TB. New iPhones with 128GB, 256GB, and 512GB storage are expected to stick with TLC NAND flash memory for the foreseeable future. While TLC flash memory remains the industry mainstream, QLC NAND is expected to account for around 20% of all NAND shipments from the second half of 2023 to the first half of 2024, indicating that its usage is still growing despite its shortcomings.
