Samsung Electronics is considering a major storage boost for its next Galaxy S flagship, but only certain models may get the speed. According to SamMobile, which points to Naver user yeux1122, the company could equip some Galaxy S27 variants with UFS 5.0 chips. The Pro and Ultra editions are in line for the upgrade, while less expensive versions might stick with the older storage standard.
The moment is key here: UFS 5.0 is transitioning from just being a standard to actual supplier samples. Back in February, Kioxia announced it had begun sending out evaluation samples of its UFS 5.0 embedded flash memory—512GB and 1TB options included. For these, the company said two lanes are capable of hitting roughly 10.8 GB/s effective read/write speeds.
Universal Flash Storage, or UFS, serves as the phone’s built-in flash memory. Mian Quddus, JEDEC Chairman, described UFS 5.0 as a “foundational technology for next-generation devices.” On the Samsung side, Jay Hyun, vice president in the NAND Planning and Strategy Group, pointed to the impact of edge-device AI on storage needs, saying performance and efficiency are “increasingly important,” with UFS 5.0 delivering “up to two times the performance of UFS 4.1.” Business Wire
Faster storage lets a phone shift hefty files, games, camera captures, and local AI models with less lag. On-device AI refers to tasks processed right on the handset, not offloaded to a cloud server.
Cost remains a sticking point. According to Gadgets360—which referenced the same Naver post—Samsung has been weighing the higher expenses and production hurdles, prompting a possible shift. The Galaxy S27 and S27+ may stick with UFS 4.0, while only the Ultra variant could upgrade to UFS 5.0.
This potential split lines up with reports of a pricier S27 lineup. The Verge, referencing ETNews, noted this month that Samsung is considering a Galaxy S27 Pro slotting between the Plus and Ultra models—no S Pen, but featuring Privacy Display tech. That would put Samsung’s roster a step closer to Apple’s tiered iPhone playbook.
The storage report hit just as fresh details on Samsung’s Exynos 2700 started making the rounds. According to Sportskeeda, a Geekbench 6 test of a chip labeled s5e9975 turned up a single-core score of 2,603 and a multi-core mark of 10,350. That’s within range of the Snapdragon 8 Elite Gen 5’s 10,732 multi-core number, though it lags behind the latter’s 3,607 single-core score.
According to Gadgets360, the yet-to-be-announced chip showed up with a 10-core setup, Xclipse 970 GPU, and about 12GB of RAM, running Android 17. If accurate, this could end up inside Samsung’s flagship phones in 2027.
The Exynos story is worth watching—Samsung continues to rely on Qualcomm for its premium devices across much of the market. Moon Sung-hoon, who serves as vice president of hardware in Samsung’s mobile division, made it clear the company wants Exynos chips “into all our lineups in the future.” He didn’t sugarcoat the challenges, though, calling mobile-chip development “difficult” and a process that takes “several years.” Android Central
This isn’t a finalized Galaxy S27 spec sheet. Benchmark data often shifts ahead of the retail chip, and that storage leak says as much about pricing pressures as it does performance—Samsung might use faster memory as another lever to push standard Galaxy users toward Pro and Ultra models.
