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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
