Raspberry Pi Zero (PIZERO) Review
Unix Bench 5.1.3
Results are an index relative to a SPARCstation 20-61 (rated at 10.0)
hdparm
Results are in megabytes per second.
The cached read hdparm test is basically a memory benchmark, and the buffered read gives a decent indication of large sequential reads.
dd
Results are in megabytes per second.
dd is a poor benchmark for server performance – but it can give a useful indication of maximum possible sequential read, write and copy speeds.
Mind you, I don’t really expect anyone to use a Pi Zero as a production server.
Power Utilization
(click on image for larger version)
As you can see the Raspberry Pi Zero idles at 120mA while powering an idle USB Ethernet adapter.
During light usage the power consumption rose to 230mA.
I found it puzzling that when the Pi Zero was powered down it was drawing 220mA!
Once I get my new power testing testbed running, I’ll do some more controlled power testing and update this review.
Documentation
Raspberry Pi Zero specific documentation is largely non-existent, however not much is really needed as the gpio pinout is identical to the A+ / B+ / Rpi 2, and basically every book, FAQ, tutorial etc. for any model Pi is applicable to the Raspberry Pi Zero (within its hardware limits).
I eagerly awaiting the release of schematics for the Pi Zero, so we can know what all those interesting test points on the bottom of the board connect to!
There is a mysterious J5 smt connector landing pad on the back as well (which may be for JTAG) – but who knows?
