A new rumor claims that some iPhone 18 Pro models will use slower QLC NAND storage, mimicking a similar 2024 iPhone 16 Pro report. It makes more sense now than it did then, but doesn’t matter much in practical usage.
This latest report suggests that Apple will use the faster TLC storage for the iPhones that people are most likely to buy. But those choosing the larger 1TB and 2TB capacities may be left with a slower QLC alternative from SK Hynix.
Companies like Apple continue to struggle to source the storage components required for new products. With that in mind, it may not be surprising to see Apple go this route. Sourcing 1TB and 2TB TLC components may be difficult, if not impossible.
And, certainly, it will be spendy given the current economic environment surrounding flash media.
However, we’ve heard this story before. And it doesn’t seem to have been accurate that time around. And as we discussed back then, it’s unclear whether the use of QLC storage would be a real issue for iPhone owners.
QLC or TLC for iPhone 18 Pro
This latest report centers around the iPhone 18 Pro and iPhone 18 Pro Max. WCCFTechshared details of a post by the leaker “Reptalica” which claims Apple will use different storage types for different models.
According to the X post, Apple will use TLC NAND provided by SK Hynix, Kioxia, and SanDisk when building 256GB and 512GB iPhone Pro/Pro Max models. The 1TB model will use a mixture of SK Hynix QLC storage and Samsung TLC chips.
It’s then argued that Apple will solely use SK Hynix’s QLC storage for the 2TB model.
A rumor, repeated
If this all sounds familiar, it’s because we saw very similar claims in January 2024, prior to the iPhone 16 Pro’s unveiling in September of that year. We were told then that Apple would use QLC storage for iPhones with 1TB of storage or more.
Getting concrete information on whether that actually happened isn’t easy. That being said, we’ve only seen reports of high-capacity iPhone 16 Pro models with the fast TLC storage. That doesn’t mean there aren’t some QLC NAND chips floating around.
If there are, we’ve yet to see one.
The differences between QLC and TLC
Triple-Level Cell (TLC) NAND flash and Quad-Level Cell (QLC) NAND flash are both types of storage. But they aren’t the same.
The iPhone 18 Pro storage may be a hot topic this hear.
One difference is the way QLC can store four bits of data per cell of memory, rather than the three of TLC. This then allows QLC NAND to store more data, which is why it’s sometimes used in larger-capacity storage. It’s also cheaper to produce.
Unfortunately, QLC is also thought to be less reliable than TLC and, importantly, it’s also slower as it is rewriting all four bits instead of the three.
How much slower in the real world, on mobile, is a matter for debate. The report notes that QLC storage is particularly slow when reading random data. But it’s unclear how that would impact the way people use iPhones.
Smartphone loads on flash storage are generally in bursts, instead of sustained transfers. As such, the difference in performance is likely to be imperceptible to users who don’t resort to benchmarking tools.
It’s also important to remember that this rumor did the rounds two years ago and, as far as we can see, turned out to be incorrect. Only time will tell if this latest report is more accurate.
Staff who use AI can end up with more to do, not less.
Think carefully about the tools you’re using and why.
Adopt a set of standards and refine your outputs.
The promise of productivity boosts from AI can come with an unwelcome side order of stress. Harvard Business Review found that AI doesn’t reduce work; it intensifies it, leading to cognitive fatigue and unsustainable hours.
While the common perception is that AI can help reduce workloads, allowing employees to focus more on higher-value and more engaging tasks, HBR’s research found that staff using AI worked more quickly and often ended up with more to do, not less.
Ankur Anand, group CIO at tech recruiter Harvey Nash, said professionals who want to avoid cognitive fatigue must understand how to use AI effectively and its potential risks.
“That focus will help to reduce the noise around the workload that AI creates,” he told ZDNET, suggesting that many people have unrealistic expectations about the productivity boost that AI will provide.
“Many organizations are telling their people, ‘We want to understand how you’re making an impact with AI,'” he said. “But these professionals are not empowered, which means that using AI adds a lot of pressure, because they need to prove themselves on their own terms.”
If you’re going to make the most of AI at work, then you’re going to have to find an effective balance between completing tasks quickly and producing high-quality work.
Here’s how the experts believe professionals can ensure they reap the benefits, not the problems, of AI — and they suggest that you’ll need to focus on three core areas: tools, guidelines, and outputs.
Limit your toolset
Alex Read, senior enterprise product manager for data at energy provider EDF UK, told ZDNET that the best way for professionals to reap the benefits, not the challenges, of AI is to be uber-focused on tools that help you produce value in your roles.
While there are thousands of potential AI-enabled services on the market, Read said sensible professionals limit their horizons.
In his own role, for example, Read focuses on how AI can help him build a data platform and update information accurately, efficiently, and productively: “Anything outside of that scope is noise for me.”
That sentiment resonated with Nick Pearson, CIO at technology specialist Ricoh Europe, who told ZDNET it’s important to take a step back and think carefully about how an AI tool can help you produce value in your role.
“If you think about the phrase ‘gen AI,’ the tech is very good, by definition, at generating outputs,” he said. “I could go to bed in the evening, set the model to work, and we could have four new IT strategies produced overnight.”
However, quantity doesn’t necessarily mean quality. Pearson suggested it’s important to focus on AI’s blind spots, particularly as most models are trained on preexisting content.
“AI can’t inspire people, per se; it can’t naturally create something new, because it’s actually quite recursive,” he said.
“And the judgment you have to put in sometimes, on top of everything else, whether it be an ethical or a capability judgment, is not there automatically in the technology.”
It’s in this gap, said Pearson, that human experts play a critical role: “We’re toying with that concern as an organization and saying, ‘Where does AI really play an important role, versus where are we upskilling people in areas that AI probably won’t play for a long time?'”
To correct this issue, HBR said companies need to adopt an “AI practice,” or a set of norms and standards around AI use that help professionals ensure they use AI in a constrained but productive manner.
At EDF UK, Read is part of an internal AI Center of Excellence in enterprise IT, which enables policy for the effective use of AI across the wider organization.
In addition to Read, who contributes input from a data-use perspective, the group includes other tech representatives, such as the firm’s senior manager of AI, principal software engineer, and principal solution architect.
“The remit of this center is to make sure that, when the federated business units are looking to build, develop, and deploy AI services, they have platforms, guidance, best practices, architectural assets, and materials to guide them on how to safely and efficiently adopt AI and operationalize it at scale,” he said.
Some of the key themes the center considers when assessing AI tools are scalability and reusability, ensuring a proposed service doesn’t replicate one already in use.
“All new tools and services related to AI will go through that hopper and funnel to understand scope and ensure the security, regulatory, and ethical side of things are understood,” he said, suggesting that all professionals should use their organization’s pre-existing guidelines to foster an appropriate exploitation of emerging tech.
“The benefit that guided approach brings is that it allows us to be clear in our messaging around what AI services can be used, how they’re used from a use-case perspective, and ultimately, what personas are allowed to use them.”
Louise Newbury-Smith, head of UK&I at technology specialist Zoom, told ZDNET that one way to ensure your outputs are constrained is to focus on prompting.
“Use simple amendments to be specific, such as ‘Give me the top three things with the biggest impact.’ That approach should guide your prompt, rather than saying, ‘Give me everything you know about this topic.'”
Newbury-Smith said the successful use of AI is all about being smart about how it’s exploited, and that effectiveness comes down to enablement and engagement. If a prompt yields too much information, refine it until you get what you need. She said this should still be faster than trying to get answers without AI.
The basic message for professionals is that effective applications of AI are all about you staying in the loop, said Bernhard Seiser, vice president of digital, data, and IT at AOP Health.
Think before you use AI, and think again before you push your outputs around the organization.
“It doesn’t help the business if you get AI-generated emails that are many pages long, and then you need ChatGPT to summarize the text,” he told ZDNET.
Seiser said that while there are certain tasks generative AI is good at and worth using for, in the end, “you need to use your brain.”
