Western Digital announced its second-generation UFS 3.1 storage solution for 5G smartphones. The new Western Digital iNAND MC EU551 delivers the high-performance storage consumers who use their phones for emerging applications like ultra-high-resolution cameras, AR/VR, gaming and 8K video.
The iNAND MC EU551 mobile storage device is the first product built on Western Digital’s new UFS 3.1 platform, first announced on May 26 at the company’s Flash Perspective event. Leveraging faster NAND, a faster controller, and an improved firmware design.
The iNAND MC EU551 delivers the following improvements over the previous generation, with up to a:
100% improvement in random read performance and up to 40% on random writes, to help support mixed workload experiences like running multiple applications simultaneously
90% improvement in sequential writes to help realize the new 5G and Wi-Fi 6 download speed potential. This gives consumers a better experience when streaming rich media files such as 8K video, as well as improved performance for applications like burst mode photography
30% improvement in sequential reads lets applications launch faster with shorter boot-up time, and enables faster upload speeds
The device is designed to meet the JEDEC UFS 3.1 specification requirements and uses the latest Write Booster technology based on Western Digital’s 7th generation SmartSLCTM. It also features Host Performance Booster version 2.0, further combining the latest advancements in the standard.
The Western Digital iNAND MC EU551 UFS 3.1 embedded flash drive (EFD) is sampling now with volume availability planned for July 2021. The storage solution is available in 128GB, 256GB, and 512GB capacities.
