The new eUFS chip measures 11.5 x 13mm the same as the one we’ve seen with the 512GB of internal storage. Well, it doubles the storage capacity by combining 16 stacked V-NAND flash memory layers and a newly developed controller. Anyways, the company did manage to maintain significant speed gains, as well.

The all-new 1TB eUFS chip from Samsung has sequential read speeds of up to 1000 MB/s and sequential write speed of 260 MB/s. With that said, the new storage can attain speeds up to 38% faster than the 512GB offering. In comparison, the standard 2.5-inch SATA SSD caps at around 540MB/s read speeds. It’s unquestionably a significant leap in the bridging gap between the technologies.
