Re: How to identify what's making one RPI3 faster?

In any case this would only test Pi hardware against SDCard hardware and software, it would not differentiate between the SDCard hardware and the different software installations. To do that you would need the copy the software images (tricky with the NOOBs one) and shuffle the images to different ...

Are there any disk read/write test utilities I could run to see how much difference that's making?

How to identify what's making one RPI3 faster?

I have three RPI3s at three different locations. The first one (we'll call Pi#1) I set up using NOOBs. It was pre-installed as part of a CanaKit. The second and third ones (Pi#2 and Pi#3) I built from individually purchased parts, and I set both up by installing Raspian directly on the micro-SD card...
