A leak from Korea announces a performance gap within the future range Galaxy S27. According to the leaker Eyes1122, only Galaxy S27 Ultra And Galaxy S27 Pro would benefit from the new storage UFS 5.0while the “classic” Galaxy S27 would remain in UFS 4.x. A choice which could create a real divide between the models from the expected release in 2027.
The site Notebookcheck summarizes the leak in an explicit title: “Galaxy S27 performance leak: Ultra, Pro models with UFS 5.0 to leave base S27 in the dust?” (Notebookcheck). No UFS 5.0 smartphone is yet marketed, but the standard has just been finalized by the JEDEC and other Android manufacturers could draw from the end of 2026. Which makes you wonder if the basic Galaxy S27 would not already be born a little behind schedule.
Galaxy S27 Ultra and Pro with UFS 5.0: what does the leak really say?
According to information collected by Notebookcheck, PhoneArena And GizmochinaTHE Galaxy S27 Ultra and the new Galaxy S27 Pro would be the first Samsung to ship UFS 5.0 memory, probably from 256 GB. Galaxy S27 standard would remain in UFS 4.0 or 4.1 with 128 GB of basic storage, as today on part of the S26 range.
Galaxy S27 UFS 5.0: what gain compared to UFS 4.0 in real life?
On a technical level, this internal storage standard that is UFS 4.0 peaks at around 5.8 GB/s in sequential reading, compared to around 10.8 GB/s for UFS 5.0. We are therefore talking about almost doubled throughput, which translates into faster application installations, shorter loading of heavy games and better responsiveness when several tasks use storage at the same time.
Associated with RAM LPDDR6 and to 2nm chips like theExynos 2700 or the Snapdragon 8 Gen 6this faster storage would also open the way to significant gains in gaming, 8K video or for artificial intelligence processing carried out directly on the device, thanks to greatly increased overall bandwidth.
Galaxy S27: will the base model already lag behind the Ultra and Pro?
On paper, the Galaxy S27 in UFS 4.0 would not be a bad student. PhoneArena reminds that UFS 4.0 remains very fast for the majority of everyday uses: navigation, social networks, streaming, classic photos. But with smartphones often kept for more than three years, the question of performance lifespan becomes central for advanced users.
In France, Ultra models are traditionally priced significantly more than the basic versions. If UFS 5.0 is really reserved for the Galaxy S27 Ultra and Pro, gamer profiles, heavy photo and video consumers or fans of local artificial intelligence tools will have an interest in targeting these variants, while the “classic” S27 will remain especially relevant for more basic use.
In any case, we will have to wait for the first independent tests to verify whether the difference promised by UFS 5.0 on the Galaxy S27 Ultra and Pro really justifies leaving the base model aside.
