(Pocket-lint) - Samsung has announced that it has started mass producing eUFS 2.1 hardware, with storage capacities of 1TB. While people have been baulking at the 512GB options available through 2018, we could see the dawn of 1TB smartphones in 2019. 

Top of the likely list is the Samsung Galaxy S10 X. This top-tier device has previously been rumoured to come with the huge internal storage capacity, but it's likely that other premium manufacturers follow suit. 

That might see the likes of Apple offering 1TB models of the next-gen iPhone - although the most recent iPhone models used Toshiba hardware according to an iFixit teardown.

Samsung executive VP of memory sales and marketing, Cheol Choi, promises that it will have this hardware available for new device launches, another hint that Samsung's next Galaxy will use it: "Samsung is committed to assuring the most reliable supply chain and adequate production quantities to support the timely launches of upcoming flagship smartphones in accelerating growth of the global mobile market." 

With the growth of 4K capture and increasing demands for large catalogues of photos or game data, capacities of smartphones have been increasing over recent years. In the current climate, most flagships start at 64GB while many now offer 128GB as standard.

The move to offer increased internal storage might also continue the trend of moving away from the microSD card. The humble microSD is often seen as a cheap way of expanding the storage that a mobile device offers, but many have avoided using it - Google and Apple particularly - but it's also a trend in recent Chinese phones - Huawei and Xiaomi for example.

Avoiding microSD means you can range more storage options for customers and for a manufacturer, that means you can set a pricing scale to match. But Samsung points out there are other advantages - reading and writing data to internal storage is much faster than to external storage - so there are huge performance gains, especially on tasks like capturing 960fps slow motion video.

Of course, Samsung announcing new hardware doesn't always correlate with Samsung's new phones, but it is an indicator of increased demands for high capacity, high performance storage in mobile devices which we'll likely see rolling out in 2019.
