Galaxy S9 Rumors: Will New Samsung Phone Feature 512GB eUFS?

Samsung 512GB eUFS

Jaesoo Han, Executive Vice President of Memory Sales and Marketing at Samsung Electronics says the following about company's vision in paving the way for mobile phones to exhibit higher levels of internal storage.

Samsung announced it has begun mass producing the industry's first 512GB embedded Universal Flash Storage (eUFS).

With Samsung's new 512GB eUFS storage, the South Korean company will soon be able to manufacture smartphones or tablets that have built-in flash storage that's the same as or even more than some desktop or laptop computers.

Coming to the intricate details of the announcement, this 512GB of eUFS storage comprises up of eight 64-layer 512Gb V-NAND chips and a controller chip, all stacked together. This effectively doubles the density of Samsung's previous 48-layer V-NAND 256GB eUFS solution, offering twice as much storage in the same amount of space.

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.

To maximize the performance and energy efficiency of the new 512GB eUFS, Samsung has introduced a new set of proprietary technologies.

The 64-layer 512Gb V-NAND's advanced circuit design and new power management technology will potentially help the Galaxy S9 to exhibit better battery life. "In addition, the 512GB eUFS' controller chip speeds up the mapping process for converting logical block addresses to those of physical blocks", the company says in its statement.

Samsung rates the new 512GB eUFS for sequential read speeds up to 860MB/s and sequential write speeds up to 255MB/s. That's eight times faster than a typical microSD card. And the phones will be advanced enough to handle multiple demanding operations at once, such as downloading a video while also searching through big files in dual-app mode. Compare that to the 100 IOPS that conventional MicroSD cards read and you have about a 400x improvement in performance. Samsung is utilizing their own 64-layer 512-gigabit (Gb) V-NAND chips for these, which will give you speedy copy and write speeds even at this size.
