No precise timeline of when these chips can be expected in mobile devices has been disclosed, beyond it being meant for upcoming flagship smartphones and tablets. An industry first, these capacious storage components are fabricated from eight 64-layer 512Gb Samsung V-NAND chips plus a controller chip in a package as pictured below. The news came just days after the Galaxy S7 and S7 edge were unveiled both of which incorporated UFS 2.0 onboard storage in either 32GB or 64GB capacities. Samsung says that its fast eUFS storage is flawless for next gen devices which could bump into "potential limitations in system performance that can occur with the use of micro SD cards". However, that barrier has now been broken as Samsung today has officially announced its new 512GB embedded UFS solution. "By assuring an early, stable supply of this advanced embedded storage, Samsung is taking a big step forward in contributing to timely launches of next-generation mobile devices by mobile manufacturers around the world". According to the company, "Consisting of eight 64-layer 512Gb V-NAND chips and a controller chip, all stacked together, Samsung's new 512GB UFS doubles the density of Samsung's previous 48-layer V-NAND-based 256GB eUFS, in the same amount of space as the 256GB package".
The new solution is also really fast, allowing users to "store approximately 130 [10 minute] 4K Ultra HD video clips", a feat that might make the experience very sluggish on current storage solutions. The company says that this is around 400 times faster than a conventional microSD card. That means you only need about six seconds to transfer an HD video clip to an SSD, Samsung says.
As for raw performance, Samsung's 512GB eUFS boasts sequential read and write speeds of up to 860MB/s and 255MB/s, respectively.
Would you still be interested in picking up the Galaxy S9 if it shipped with 500GB of internal flash storage instead of a microSD slot?
Another possible market is the imminent Microsoft/Qualcomm Windows-10-on-ARM laptops, which The Register understands will all-but-expect an LTE connection but will not be made worse by 512GB of power-sipping storage. As usual, the Galaxy S series will kick off Samsung's flagship smartphone campaign in 2018 and later followed by the Galaxy Note 9.
