By maintaining the 2.5 inch form factor, they make it easier for PC manufacturers to offer an option of either HDD or SSD in what is otherwise the same PC. Then the customer can decide the economic tradeoff between cost and speed based on individual needs.
"The unit is available in capacities up to 512-Gbyte and comes with a 6-Gbyte per second SATA interface and it comes in a 2.5-inches form-factor but at only 9.5-mm or 7-mm deep. "
I am not sure why they stick to this 2.5inch formfactor for SSDs, when they can make it really much smaller. Because of the form factor, ultra thin laptops like macbook air, directly uses a smaller PCB with a few flash chips sticked on it. And this reduces the upgrade options for the notebook.
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.
