Selected Answer: A
if you plan to store extensive historical data for a large number of remote-sensing devices and then use the data to generate daily reports, the cost savings for HDD storage might justify the performance tradeoff. On the other hand, if you plan to use the data to display a real-time dashboard, it probably would not make sense to use HDD storage—reads would be much more frequent in this case, and reads that are not scans are much slower with HDD storage.

A. When you create a Bigtable instance you have to choose either SSD or HDD. The SSD options says, “Lower latency and more rows read per second. Typically used for real-time serving use cases, such as ad serving and mobile app recommendations”. User facing plus low latency plus read intensive equals SSD.
