Western Digital Corp. introduced a portfolio of iNAND embedded flash drives (EFDs) to empower smartphone users to unlock the potential of today's data-driven applications and experiences.

Leveraging company's 64-layer 3D NAND technology and UFS and e.MMC interface technologies, the intelligent, new iNAND 8521 and iNAND 7550 EFDs deliver performance and capacity.

When designed into smartphones and thin, lightweight computing devices, they accelerate the possibilities of a range of demanding data-centric applications, including augmented reality, high resolution video capture and rich social media experiences, as well AI and IoT experiences at the 'edge.'

The volume, velocity, variety and value of data continues to grow and evolve across big data, fast data and personal data. Many consumers around the world will experience this confluence of data on their smartphone.

"By end of 2018, we estimate that average storage capacity will climb to over 60GB per smartphone globally to support the growing proportion of rich multimedia content and data-driven experiences from artificial intelligence to augmented reality on the devices," said Neil Shah, research director of devices and ecosystems, Counterpoint Technology Market Research. "This warrants a move to advanced 3D NAND embedded flash storage solutions, which will drive these richer experiences even further."

"In addition to 360 video and multi-lens cameras, the emergence of AI in mbile apps for more immersive experiences will propel the data-centric nature of smartphones to new levels," said Christopher Bergey, VP of embedded and integrated solutions, Western Digital. "Our innovative new iNAND solutions create environments for data across today's most intensive mobile applications and experiences to thrive. We brought together Western Digital's industry-leading X3 3D NAND technology and new enhancements to our unique application-aware SmartSLC technologies to provide customers with our most intelligent and highest performance iNAND devices to date. These new additions to our iNAND portfolio position us well to continue addressing the rising mobile data demands of the dynamic global mobile market."

iNAND 8521 EFD Delivers 5G Network-Ready Performance for Mobile Devices
Designed for data-intensive users, the iNAND 8521 EFD utilizes the UFS 2.1 interface and Western Digital's new fifth-generation SmartSLC technology to deliver up to double the sequential write speed (1), and up to 10 times the random write speed (2) compared with the company's previous iNAND mobile solution for flagship smartphones, the iNAND 7232 EFD. Quickly and intelligently responding to users' application performance needs, it enables rapid virtual reality game play and fast downloading of HD movies. The high data transfer speed of the iNAND 8521 EFD also enables mobile users to take advantage of the latest Wi-Fi speeds and network enhancements as service providers transition to 5G.

iNAND 7550 EFD for Nimble, High Capacity Mainstream Smartphones
The iNAND 7550 EFD enables mobile manufacturers to create cost-effective smartphones and computing devices that feature storage to meet the needs of increasing consumer content while providing fast and engaging application experiences. Built on the e.MMC 5.1 specification, it is the company's highest performing iNAND EFD based on the widely used e.MMC interfaces to date, and delivers sequential write performance of up 260MB/s and random R/W performance of 20,000 IO/s and 15,000 IO/s respectively (3). This enables the iNAND 7550 to enhance boot-up and application launch times.

Marketed under the SanDisk brand, the iNAND 8521 and iNAND 7550 EFDs are the latest additions to the iNAND family, which has been trusted by major smartphone and tablet manufacturers around the world for over a decade.

Western Digital is currently sampling iNAND 8521 and iNAND 7550 storage solutions to OEMs in capacities up to 256GB (4).

(1) Offers sequential write speed up to 500MB/s compared to 160MB/s offered by iNAND 7232. Based on internal testing; performance may vary depending upon drive capacity, host device, file attributes, OS and application.
(2) Offers random write speed of up to 45,000 IO/s compared to up to 4,000 IO/s offered by iNAND 7232. Based on internal testing; performance may vary depending upon drive capacity, host device, file attributes, OS and application.
(3) Based on internal testing; performance may vary depending upon drive capacity, host device, file attributes, OS and application.
(4) 1GB = 1,000,000,000 bytes. Actual user storage less.
