I think you have RAZR2 description incorrect - USB performance numbers are those of a USB-HS device but only GSM version of RAZR2 (V8) has USB-HS - but it has 2GB of internal memory but no memory card. 3G version of RAZR2 (V9) has some internal memory and a removable card but does not has USB-HS so it can not get the throughput rates you are measuring.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
