iNAND® IX EU312 Industrial Embedded Flash Drive

Western Digital’s iNAND® IX EU312 EFD Industrial embedded flash
devices, with Universal Flash Storage (UFS) Version 2.1 interface
and 3D NAND, provide high reliability and endurance for industrial
and surveillance applications across a wide range of operationalrequirements.

Product Highlights

The iNAND® IX EU312 Embedded Flash Drive (EFD) is Western Digital’s mostadvanced flash storage solution for industrial and surveillance applications.
Built with optimized 3D NAND technology and a fast UFSv2.1 interface, theiNAND IX EU312 EFD offers superior read and write performance, delivering anembedded storage solution for the most data-intensive industrial applications.
More than twice the performance of e.MMC products, the iNAND IX EU312 isdesigned with the higher endurance and the extended temperature ranges
needed for the demanding use cases of industrial environments and surveillance.

n Advanced memory management firmware features,
including strong ECC, read refresh, wear-leveling andbad block management

This industrial product undergoes rigorous qualification and production testing, thereby reducing the complexity and number of qualification cycles forsystem manufacturers. The device uses a LDPC ECC engine and optimized
3D NAND that results in a highly robust, high endurance and reliable product.
In addition, an integrated SLC cache with extended data retention leads toa lower UBER at any given point over the life of the product.
