In a recent report from DigiTimes, it has been suggested that the forthcoming iPhone 16 Pro models, featuring 1TB storage configurations, may experience adjustments in read and write speeds as a cost mitigation strategy. This potential modification is reportedly tied to Apple’s active consideration of transitioning to higher-density Quad-Level Cell (QLC) NAND flash memory for its 1TB iPhone variants, a departure from the current use of the more expensive Triple-Level Cell (TLC) NAND.

The envisioned shift to QLC NAND is driven by Apple‘s goal to maximize storage capacity in a more compact space while reducing costs. However, this choice entails a trade-off, as QLC NAND is known for slower read and write speeds and a potentially lower level of durability and reliability compared to TLC NAND, particularly under frequent write operations. To address these challenges, Apple is expected to implement specific optimizations.
The report further speculates that the adoption of QLC NAND might pave the way for Apple to introduce iPhones with storage capacities of up to 2TB for the first time. Currently, the 1TB iPhone 15 Pro Max is priced at $1,599, representing a $200 premium over the 512GB model. Consequently, any prospective 2TB model would need to find a balance between cost-effectiveness and the ability to accommodate compact flash storage within the device.
Regarding iPhones with storage capacities of 128GB, 256GB, and 512GB, the report suggests a continued preference for TLC NAND in the foreseeable future. Despite the prevailing use of TLC NAND in the industry, the increasing adoption of QLC NAND is evident, with an anticipated share of approximately 20% of all NAND shipments expected from the second half of 2023 to the first half of 2024. This trend indicates a growing acceptance of QLC NAND, despite its inherent drawbacks, signaling its integration into the mainstream storage landscape.
