Samsung Touts First Embedded 512 Gigabyte Flash Storage for Mobile Devices

According to Samsung, its new 512GB eUFS offering features eight 64-layer 512Gb V-NAND chip and a controller chip that stacked together in one single solution. By comparison, most smartphones today - including the iPhone X - are capped at 256GB of storage. Samsung claims that the 512GB chip can hold approximately 130 ten minute 4K Ultra HD videos, which is good news for all the phones that come with 4K video recording capability. That sort of content is becoming more popular as sharper displays and enhanced cameras are included on smartphones.

Samsung could be gearing up to use its new storage chip in the upcoming Galaxy S9 and Note 9 that could see the largest internal storage capacity to date in Galaxy devices.

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. "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". Using UFS proved to be the right decision for Samsung, as it achieved much better performance than eMMC, which was predominantly used by Android phones at the time.

This doubles the density of Samsung's previous 48-layer V-NAND-based 256GB eUFS, and in the same amount of space as the 256GB package.

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.

Samsung is promising speeds of 860MB/s while reading and 255 MB/s while writing the data. That means you only need about six seconds to transfer an HD video clip to an SSD, Samsung says.

As we don't know how long the firm's been holding onto the technology, it's tough to say whether it will make the cut - but if it was on the assembly line before the Galaxy S9 entered production at the beginning of last month, it could very well be on board. However, if the company starts using this storage module, we may be facing the prospects of losing the microSD card slot.
