While SSDs are considered to be a bit more durable than HDDs due to the fact that they have no moving parts, they do go through wear and tear in the form of write cycles, and unfortunately it looks like the iPhone 14 could actually feature the use of storage that might have lower write cycles compared to its predecessors.
This is according to a report from DigiTimes who claims that for the iPhone 14, Apple will apparently be switching over to the use of QLC NAND flash storage, which could result in lower write cycles. There are apparently two reasons for this. One of those reasons is due to the global chip shortage that is expected to last into 2022, but the other could also be in anticipation for bigger storage iPhones.
One of the benefits of QLC over TLC or MLC NAND flash is that it allows more capacity in the same area, meaning that it would allow Apple to fit more storage without having to make the iPhone bigger/thicker. As our media files get bigger and apps become more powerful, we imagine it’s only a matter of time before Apple starts offering iPhones with more storage, and QLC NAND flash is one of the ways the company could do it.
That being said, we doubt that switching over to QLC means that your next iPhone’s storage will fail after a few months, but for those who tend to hold onto their smartphones for 3-4 years or longer, then maybe this could have an impact on its longevity. Then again, it really depends on how you use your device, so your mileage may vary.
