New tests suggest Apple skimped on a key iPhone 6 component and it’s causing problems
Certain iPhone and iPhone Plus owners, as well as some iPad users, have complained about random crashes and reboots on smartphones that have GB or GB of storage and hold large libraries of apps. Various reports trying to explain the problem have identified the type of NAND memory chosen for these iPhone models as the main culprit, with some suggesting that Apple is already considering moving from triple cell TLC NAND memory to multi-level cell MLC storage in future iPhone versions.
Apple has not confirmed those reports, and has not explained why GB iPhone and GB iPhone Plus devices seem to crash in certain circumstances. But a new report from Korean publication KBench shows benchmark tests for both TLC and MLC NAND memory modules used in GB iPhone units, and they reveal that the latter offers a better performance than the former.
Previous reports have said that Apple may have chosen TLC NAND because it’s more affordable than MLC. The company this year significantly increased storage options for new iPhone purchases, making the GB versions cheaper than in previous years, and introducing a GB option.
The same reports also said that TLC NAND is slower than MLC and SLC single-level cell, even though it can store more data per cell. The benchmarks seem to indicate that MLC is superior to TLC when it comes to writing speeds, though TLC writing speeds appear to be significantly better for smaller files, but doesn’t explain the crash issues encountered by iPhone owners.
