So do not be surprised if flagship phones next year - maybe even the Galaxy S9 and the Galaxy Note 9 - would top out at 512GB internal storage. Android benefits from the ability to install an external memory card in most devices to provide additional storage but that could be a thing of the past thanks to the internal storage capacity in Samsungs new chip hitting 512GB.
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.
Taxable Tuition = Trouble for Graduate Students
This specific provision was included in a tax plan passed by the United States House of Representatives earlier this month. However, students who are working toward an advanced degree are among those who could be paying more under the new plan.
With 512GB of storage, Samsung says you'll be able to store around 130 4K videos (3840 x 2160) that are each 10-minutes long on a smartphone. Despite the increased number of layers, it still have the same size as the company's previous 48-layer V-NAND 256GB solution.
Samsung also injected its 512GB eUFS solution with a new of proprietary technologies, including an advanced circuit design and new power management technology in the controller to minimize energy consumption. It also boasts a random read speed of 42,000 IOPS (input/output operations per second) and a write speed of 40,000 IOPS. While the company's press release does not specifically mention which version of the UFS interface had been implemented, Samsung did state that the storage package could attain "sequential read and writes reaching up to 860 megabytes per second (MB/s) and 255MB/s respectively" putting it very much in the ballpark of UFS 2.0. According to Samsung, the random writes of the UFS package are approximately 400 times faster than the 100 IOPS speed of a conventional microSD card.
Finally, Samsung noted that it intends to "steadily" increase production volume for its 64-layer 512Gb V-NAND chips, while continuing to expand its 256Gb V-NAND production. With 512GB of onboard storage, it would, for most people, eliminate the need for supplementary storage options, such as microSD cards.
