Western Digital’s UFS 3.0 EFD Empowers 5G Mobility

Turbo Sequential Write Speed and High Capacities Maximize User
Experience in the 5G Era

SAN JOSE, Calif.–(BUSINESS WIRE)–Western
Digital Corp. (NASDAQ: WDC) is enriching smartphone users’ mobile
experience in the 5G era with a new embedded flash drive (EFD) that
provides the speed and capacity necessary to maximize the capabilities
of ultra-high-end smartphones and mobile devices. Built on the company’s
advanced 96-layer 3D NAND, the iNAND®
MC EU511 supports Universal Flash Storage (UFS) 3.0 Gear 4/2 Lane
specifications. The advanced iNAND SmartSLC Generation 6 propels turbo
sequential write speeds up to 750MB/s*, enabling a 2-hour movie download
in only 3.6 seconds¹.

The 5G standard promises ultra-fast transfer speeds, low latency, lower
power consumption and high network capacities for all mobile and edge
devices. These capabilities necessitate the high-speed data interfaces,
such as UFS 3.0, transforming not only smartphones but billions of
interconnected Internet of Things (IoT) devices.

“Smartphones are increasingly becoming the hub of all things connected,”
said Oded Sagee, senior director, Devices, Western Digital. “High speed
5G networks are set to deliver data at up to 100X the speed of previous
generations and amplify AI on many devices. Artificial Intelligence (AI)
powered by integrated neural processing units (NPU) with access to big
and fast data will transform how we use our smartphones. Real-time
computing on the edge will be in such high demand that high standards of
data capturing and accessing are fundamental. With our UFS 3.0 embedded
flash drive, we are enabling users to experience the new power of 5G
applications, on-demand, seamlessly and instantaneously.”

Powered by the higher performance of a UFS 3.0 flash interface, 5G
mobile devices will provide greater performance and lower latency for
applications such as augmented reality, virtual reality (AR/VR) and
mobile gaming. Additionally, high network speeds will enable consumers
to quickly download and view ultra-high-resolution photos and 4K/8K
media on mobile devices.

Ready for 5G devices with iNAND® MC EU511 EFD

The iNAND MC EU511 leads the industry with turbo sequential write speed
up to 750MB/s and sequential read speed that is nearly double its
predecessor. With increased random read/write performance and capacities
ranging from 64GB to 512GB, iNAND MC EU511 is ready to empower mobile
devices for the coming 5G revolution. Western Digital is currently
sampling the iNAND MC EU511 EFD solutions with OEMs. For more
