Western Digital Spins Off Flash Business, Launches High-Capacity 26TB HDD for NAS Applications

March 12, 2025 – Western Digital (WD) has officially completed the separation of its NAND Flash business, transferring it entirely to its wholly-owned subsidiary SanDisk. This strategic shift positions SanDisk as the sole operator of WD’s NAND Flash and SSD business, while Western Digital will now focus exclusively on the HDD (hard disk drive) market.

New 26TB WD Red Pro HDD for NAS Systems

This high-capacity drive also caters to direct-attached storage (DAS) solutions, making it an ideal choice for creative professionals and enterprises that require reliable, high-performance storage.

Cutting-Edge OptiNAND Technology for Enhanced Performance

The WD Red Pro 26TB HDD leverages WD’s OptiNAND architecture, which integrates an iNAND embedded universal flash drive (EFD) directly onto the PCB (Printed Circuit Board). It also features a 512MB cache, which, combined with advanced storage management algorithms, significantly improves the capacity, reliability, and performance of the drive.
