iPhone 16 Pro iPhone 16 Pro/ProMax - Storage Speeds

[TL24]

Recently came across this thread on Reddit: Apple did switch to QLC for the larger storage iPhone 16 models. Likely means a hit to performance and reliability compared to the TLC versions previously.

With that said, I can't honestly tell as my 16 Pro 512GB just zips right through everything I'm throwing at it and is smooth as butter on iOS 18.1 B5. Does anyone know how we can tell if we have QLC or TLC?

UPDATE: Used 3uTools and it says my 16 Pro 512GB uses a Toshiba TLC NVMe.

The ideal test is to measure write performance when the drive is mostly full.

All SSDs will write somewhat slower when mostly full, but QLC drives typically crater to <5% of peak write performance.

The Orico O7000 uses the very popular Maxiotech MAP1602 controller, paired with QLC NAND, to build a highly affordable soild-state drive. The real-life testing in our review confirms: this is the fastest QLC based SSD, even beating most other TLC SSDs on the market.

One can also try to decode the model number of the NAND chip, but Apple often sources unique models without public specifications.

Fewer reviews take the time to study long-term usage, like when the phone is full, even though loads of us use phones in that state.

@TL24 you can use https://www.3u.com/productsIos and then check 'Hard Disk Type'

My 16PM 1TB has TLC, so I think this thread is bunk.
TLC, S5E, from Toshiba.

Same, my 16PM 512GB is TLC Hynix.

Mine 512 is TLC but it says only TLC, no external manufacturer, where to look for more details?

I just used 3uTools and mine says my iPhone 16 Pro 512GB is a Toshiba TLC NVMe. So I'm not exactly sure how some people are saying it's a QLC, maybe those that have a 256GB and lower can check their device too?

@TL24 nobody actually said they had QLC, only rumours and then Apple Support, but seems like they were wrong. 256, 512 and 1TB are now confirmed TLC

Can you screen shot that? I’m trying to see and show to this to others. Thanks for sharing. It’s been hot topic last couple weeks.
