Samsung Starts Production of 1 TB eUFS 2.1 Storage for Smartphones



Samsung said it had started a mass production of its eUFS 2.1 storage solution featuring 1 TB capacity for smartphones. Apart from its massive capacity, a SATA SSD. Samsung expects the device to be used by high-end smartphones “soon”.

Samsung's eUFS 2.1 standard 11.5 mm x 13 mm package and is based on a 512 Gb V-NAND flash memory dies as a proprietary controller. The drive is compatible with the UFS 2.1 interface that is relatively widespread these days.

When it comes to performance characteristics, Samsung claims a 1000 MB / s sequential read speed as well as up to 260 MB / s sequential write speed. Random read / write performance of the 58K / 50K of read / write IOPS. The new drive is tangibly faster when it comes to Samsung's previous-generation 512 GB eUFS 2.1 solution, but also higher performance. Obviously, any eUFS 2.1 device is orders of magnitude faster than any microSD card.

What is a bit surprising is the Samsung UFS 3.0 specification that is supported by Samsung's Own Exynos 9820 mobile SoC or will support it shortly).

Samsung has not disclose pricing of its 1 TB eUFS 2.1 drive, but it will be smartphones featuring the chip.

In addition to announcing its new eUFS 2.1 storage solution for high-end smartphones, Samsung also said it would expand production of its 5th Gen 512 Gb V-NAND memory later in the first half of 2019, which will enable it to boost the efficiency of eUFS drives in general and 1 TB devices in particular.
