Enhanced eMMC Performance for Ruggedized Handhelds

With mobile solutions installed in more than 80 countries over 40 years, a leading European manufacturer of handheld mobile computers has earned their reputation for innovation around the world. Their products are notable for advanced technology such as RFID and speech, as well as their performance, durability, and low lifetime cost of ownership. The company’s open and collective approach to innovation, quality and service pays dividends in dependable products demanded by enterprises operating in harsh environments.

These ruggedized handheld computers are the toughest available but still deliver serious processing power and the lowest TCO (Total Cost of Ownership). Recently, the company set out to build the most adaptable handheld platform in the industry, allowing devices to be flexibly configured for a wide variety of users and environments. Products built on this platform are assembled using shared components and tools, so devices can be customized through collaborative innovation with customers and partners, giving end users a product that is built for their specific needs. New technologies can be added quickly and cost-effectively, with minimal disruption and downtime. The platform enables organizations to save up to 30% in hardware costs over the life of the product. The newest PDA built using this platform boasts an impressive list of features that help customers minimize downtime, maximize productivity, and reduce costs in the long-term, enabling businesses to work harder and smarter in the field.

Adding to the flexibility of this platform is a Texas Instruments OMAP3 processor and e•MMC data storage. As initial design work progressed, however, the company’s engineering team experienced unacceptably slow performance when writing data to the e•MMC storage memory. Investigation into the problem revealed a compatibility issue between e•MMC and TFAT, the default file system included in the Windows Embedded CE and Windows Mobile operating systems. It quickly became clear that finding a replacement file system was the only cost-effective option.

In their search for a new file system, the team discovered Datalight Reliance Nitro, a true transactional file system. Reliance Nitro was designed specifically for e•MMC and other types of flash memory, and can be easily customized for the performance and data integrity needs of any use case. As part of their evaluation, engineers began working with the Datalight support team to determine the optimal performance settings for Reliance Nitro. The team was impressed by the depth of knowledge demonstrated by Datalight support engineers around e•MMC, and by the substantial improvements to write and read performance they were able to achieve. In choosing Reliance Nitro, the company discovered a solution that not only optimized the performance of their e•MMC parts, but will provide rock-solid data integrity for customers now and in the future.
