Samsung has begun mass production of eUFS 3.0 storage chips for smartphones and other devices that the company says offers data transfer speeds that are twice as fast as eUFS 2.1.

128GB and 512GB eUFS 3.0 versions should be available this month, and Samsung says it’ll begin shipping 256GB and 1TB eUFS 3.0 products in the second half of 2019.

According to Samsung, the new storage solution can hit sequential read speeds as high as 2,100 MB/s and write speeds up to 410MB/s.

That’s up from 1,000 MB/s and 260 MB/s, respectively, for the 1TB eUFS 2.1 solution Samsung launched just last month.

Performance gains are a little less impressive when you look at random read/write speeds, which have jumped from 58,000 IOPS to 63,000 IOPS for read and from 50,000 to 68,000 IOPS for write speeds.

Still, we’re looking at mobile storage that rivals the performance you’d expect from an SSD designed for laptop or desktop computers.

There’s no word on when we’ll start to see consumer devices that use the new storage technology.

  1. Just another reason it’s not a good time to buy a smartphone–unless you’re breaks or is lost.

    1. On the contrary, where phones have the biggest downsides are battery life, speaker quality, software, durability, single-thread performance, camera quality, graphics performance, repairability, memory performance, multicore performance, storage performance, charging speeds, display quality.

      This year, battery life and single-thread performance will increase much more than the last 3-years thanks to the jump in microarchitecture and lithography (QSD 820QSD 855). There won’t be any improvements in memory performance and storage performance. And we’ve peaked as far as display quality (S10+/Xperia 1) is concerned. But there will still be some increases to graphics performance, multicore performance, and camera performance. As far as audio quality, durability, repairability and software is concerned… that seems to be upto the manufacturers (or specific device) and isn’t quite as predictable.

      So if you have a 2016 device, it hasn’t been “worth it” to upgrade until 2019. You’re effectively going from a device with 3,000mAh 14nm Quad Cortex A72, decent graphics and decent camera with 15W charging…. to a device that has 4,000mAh 7nm Quad Cortex A76, better graphics and good camera with 40W charging.

  2. Does it make sense to put this type of storage into cheap notebooks? I guess it’s cheaper than SSD. I guess it should be still better than eMMC.

  3. Are you sure about this? If random writes are greater than reads then it is definitely impressive.
