Raspberry Pi Mass Storage Power Consumption

As described in my original twitter thread

How do mass storage devices impact power consumption of Raspberry Pi?

I wanted an idea of UPS runtime, so I scripted a benchmark to run at boot: - write 100x 128MB files - flush cache w/1GB file - read 100x 128MB files - shutdown

Measure duration, energy consumed, etc
