The Industrial iNAND IX EM1321 Embedded Flash Drive (EFD) is Western Digital’s
most advanced e.MMC flash storage solution for industrial applications, with highreliability and endurance across a wide range of operational requirements.
Designed and tested to withstand demanding environmental conditions, theseindustrial grade flash devices feature advanced flash memory management
firmware that provides enhanced power immunity, ECC, wear leveling, and badblock management. Data intensive applications can rely on the EM132 to capture
every critical moment, log each event, and to ensure quality-of-service to endusers.
The Smart Partitioning feature of the iNAND IX EM132 EFD Industrial flash devices
enables Boot partitions, RPMB, multiple General-Purpose Partitions, User Data
Area and Enhanced User Data Area, providing OEMs the flexibility to choose
different attributes on a single device depending on storage requirements.
With optimized 3D NAND memory, iNAND IX EM132 offers a significant capacity
increase compared with the previous generation of iNAND products.
