Western Digital Revealing 256GB iNAND 7350 e.MMC Flash Drive

Western Digital Corp. (WDC) introduced the iNAND 7350 storage solution, an advanced and high capacity embedded flash drive (EFD).

Leveraging firm’s 3D NAND and intelligent fourth-generation SmartSLC technology, iNAND 7350 delivers up to 256GB ⁽¹⁾ of reliable and responsive embedded storage that is for data-rich applications and next-generation mobile experiences.

“Our new 256GB iNAND 7350 is the highest capacity embedded storage device available today on e.MMC, the industry’s most proven interface,” said Christopher Bergey, VP, embedded and integrated solutions, Western Digital. “By combining our 3D NAND technology and latest application-aware architecture, we have built the iNAND 7350 storage device to deliver an exceptional balance of performance, capacity and cost-efficiency. This can enable smartphone manufacturers to introduce mainstream devices that offer the high capacity consumers crave and deliver outstanding application experiences – from high-quality 4K Ultra HD video playback to next-generation augmented reality (AR).“

Memory-level and application architecture advancements enhance capacity and performance
Designed with smartphone OEMs’ needs, the iNAND 7350 is the first company’s embedded storage solution to leverage the firm’s 3D NAND technology, which helps enhance the device’s performance, capacity and data retention.

This addition to the SanDisk-branded iNAND family of solutions is the company’s best performing embedded mobile storage device to date. The enhanced SmartSLC technology inside iNAND 7350 enables it to respond on-demand to deliver the ideal level of application performance needed. This proprietary technology also helps to enhance the device’s sequential write speed, allowing it to provide speeds of up to nearly 2Gb/s ⁽²⁾. This translates to a better experience for consumers who can now transfer a 1GB digital file up to 40% faster compared to smartphones built with the company’s previous generation embedded mobile device. ⁽³⁾ In addition, the iNAND 7350 delivers fast random read performance, offering speeds of up to 22,000 IO/s  ⁽⁴⁾ – the fastest random read performance of any e.MMC device ⁽⁵⁾.

With these advancements, the iNAND 7350 can support advanced Wi-Fi and cellular speeds, as well as popular applications such as social media. It can also enhance the performance of consumers’ most demanding experiences, such as 4K Ultra HD video capture, AR and virtual reality, and professional-quality photography.

Currently sampling iNAND 7350 storage solution to select OEMs, with availability beginning in 2Q17.
