Samsung could level up Galaxy S27 series performance away from the silicon

The next Galaxy flagship's best speed upgrade has nothing to do with its processor and everything to do with storage.

When Samsung fans debate next-generation performance, the conversation often centers on the processor. However, a new leak suggests that the Galaxy S27 series could get a substantial speed boost from somewhere that isn’t as glamorous or popular: its storage.

According to a Korean blog post, Samsung is considering UFS 5.0, the next generation of Universal Flash Storage, for its lineup. But, like all good things, the rumor comes with a catch. The faster storage might only be available on select Galaxy S27 models, not the entire lineup.

What makes UFS 5.0 such a big deal?

Currently, the Galaxy S26 lineup comes with UFS 4.0 storage, which provides up to 4.2GB/s of data transfer speeds, regardless of the model you pick. While UFS 4.0 is already quite fast, some smartphones like the OnePlus 15 already offer UFS 4.1 storage, which offers an interactive yet impactful boost to the storage read/write speeds.

UFS 5.0 chips, on the other hand, are expected to deliver sequential read speeds of up to 10.8GB/s, which is more than twice the theoretical limit of UFS 4.0. In other words, the UFS 5.0 storage on select Galaxy S27 models could bring their read/write speed in the same ballpark as high-end desktop PCIe Gen 4 SSDs.

Faster storage on the Galaxy S27 could unlock snappier app launches, quicker image processing, and stronger on-device AI performance without requiring outsourcing heavy features to the cloud.

Why won’t every Galaxy S27 get UFS 5.0 storage?

It’s more about the component cost than Samsung’s intention to provide its users with an upgrade. Citing rising memory prices and higher mass-production costs, the leak claims the exceptional storage upgrade could be reserved for premium configurations.

I’m thinking the 512GB variants of the top-tier Ultra and the Plus variants, but it would be a welcome addition if the baseline Galaxy S27 also gets UFS 5.0 storage on its 512GB version. Crucially, there might not be an upgrade in the “basic capacity configuration,” which isn’t exactly crystal clear, but likely means that the lineup will stick with 256GB of storage across its base models.

The dream of uber cheap phones for kids and grandparents is effectively dead, thanks to AI

AI's demand for memory chips has made budget smartphones unprofitable to build.

Electronics, Mobile Phone, Phone

That $100 phone you were going to grab for your kid's first device, or hand down to grandma, could become a dream in a while. AI's hunger for memory chips just made the entire budget phone category borderline impossible to build.

So how bad are we actually talking?

Apple’s new Upgrade program launches on Tuesday with major changes

Apple's new leasing program might drop AppleCare coverage from the bundle.

iPhone 17 Pro Max

Buying your next Apple device could soon look like leasing a car. Apple is launching its new Apple Upgrade program on Tuesday, July 28, replacing new enrollments in the long-running iPhone Upgrade Program with a lease-based option that covers iPhones, iPads, Macs, and Apple Watches.

Backed by Klarna, the program is designed to lower the upfront cost of Apple's premium devices, but it is also raising questions about whether you'll actually own what you're paying for.

Setting up your dorm desk? These are the phone stands I’d actually spend my money on

From a $2 folding stand to a three-in-one Apple charging dock, these are the phone stands worth setting up this semester.

A phone stand is one of the smallest purchases on any back-to-school list, but it's also one of the easiest to get wrong, especially since there are dozens of options available on Amazon. A good phone stand is one that does its job well and, more importantly, doesn't put much of a dent in your budget.

This is one of those product categories where you don’t need to spend big, unless a MagSafe dock or a multi-device charging stand is genuinely useful for your desk or dorm setup. That is why this list begins with the most affordable options and works its way up to the more expensive ones. From a two-pack that costs about as much as a coffee to a three-in-one Apple charging station, I picked eight of Amazon's best-reviewed phone stands worth considering this back-to-school season.
