Samsung's announced it's doubled the size of its largest Universal Flash Storage (eUFS) product to 512 gigabytes and started mass production of the chips. Although most flagships stop at 128 GB these days, the tech giant continues its push in this market by starting to manufacture the first 512 GB eUFS embedded storage solution. The top candidate right now is the Galaxy S9, which is expected to be Samsung's next flagship Android smartphone.
MicroSD storage seems to be the main target with this innovation, as Samsung suggest embedded storage is more stable and and less limiting than current external storage cards used in mobile devices. This is 10 times more than what a 64GB phone is capable of storing.
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.
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.
Samsung says that it has introduced a new set of proprietary technologies to maximize performance and energy efficiency. In addition, the 512GB eUFS' controller chip speeds up the mapping process for converting logical block addresses to those of physical blocks.
As for raw performance, Samsung's 512GB eUFS boasts sequential read and write speeds of up to 860MB/s and 255MB/s, respectively. That's eight times faster than a typical microSD card.
For random operations, the new eUFS can read 42,000 IOPS and write 40,000 IOPS. This will improve the speed of storage-intensive tasks such as high-resolution burst photos, file searches, and downloading videos in dual app mode, the company states. No, not really. That's why Samsung says it is going to steadily increase its production volume for both 512 GB and 256 GB V-NAND chips. Compare that to the 100 IOPS that conventional MicroSD cards read and you have about a 400x improvement in performance. It's a remote possibility for now, and even if flagships are released with variants having 512GB of storage, they are sure to be priced extremely high.
