When Samsung fans discuss next-generation performance, the discussion often revolves around the processor. However, a new leak suggests that the Galaxy S27 series could get a significant speed boost from a place that isn’t as glamorous or popular: 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 has a catch. The faster storage may 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 series is equipped with UFS 4.0 storage, which offers data transfer speeds of up to 4.2 GB/s regardless of the model you choose. While UFS 4.0 is already quite fast, some smartphones like the OnePlus 15 already offer UFS 4.1 storage, which interactively yet effectively increases the read/write speed of the storage.
UFS 5.0 chips, on the other hand, are said to deliver sequential read speeds of up to 10.8 GB/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 its read/write speeds to the same level as high-end 4th generation desktop PCIe SSDs.
Faster storage on the Galaxy S27 could enable faster app launches, faster image processing and stronger AI performance on the device without having to outsource extensive functionality to the cloud.
Why doesn’t every Galaxy S27 get UFS 5.0 storage?
It’s more about the component cost than Samsung’s intention to offer its users an upgrade. Citing rising memory prices and higher mass production costs, the leak claims that the exceptional memory upgrade could be reserved for premium configurations.
I’m thinking of the 512GB variants of the top Ultra and Plus variants, but it would be a welcome addition if the base model Galaxy S27 also got UFS 5.0 storage in its 512GB version. Crucially, there may not be an upgrade in the “base capacity configuration”, which isn’t entirely clear but likely means the range will remain at 256GB of storage across all base models.
