> The Pro matches the Ultra's 1TB of storage but not its memory, so the Ultra keeps one clear edge. Samsung still hasn't decided whether its top two phones get faster memory chips.

Leaker Lanzuk published [memory and storage configurations for all four Galaxy S27 phones](https://www.androidauthority.com/samsung-galaxy-s27-memory-storage-configurations-leak-3713926/) on the Korean blog Naver, citing Weibo and Korean industry sources. Tipster @wallegalaxy posted the same split on X. Every model starts with 12GB of RAM. The S27 and S27 Plus come in 256GB and 512GB, and some regions may also get a 128GB version. The new S27 Pro goes all the way to 1TB of storage without adding memory. Only the Ultra reaches 16GB, and only in its 1TB configuration.

Lanzuk also expects the Pro and Ultra to move to LPDDR6 memory and UFS 5.1 storage, newer and faster chip standards than the LPDDR5X and UFS 4.0 in the [Galaxy S26 Ultra](https://idevice.com/phones/galaxy-s/roadmap/s26-ultra). That part isn't settled. Samsung [hasn't made a final call yet](https://sammyguru.com/samsung-galaxy-s27-ultra-lpddr6-ufs-5-1-rumors/), according to Korean media reports, most likely because the newer parts cost more while memory prices climb during a shortage. The S27 and S27 Plus are expected to keep the older chips either way.
