Re: How gets power usage measured in SSD tests?

Ditching the shunt resistor might well help the accuracy but trying to read 'simultaneous' measurements from several multi-meters at the same time (I assume to get power consumption) would be potentially rather inaccurate. The quarch unit ( http://www.quarch.com/products/qtl1455.html ) runs multiple...

Re: How gets power usage measured in SSD tests?

Out of interest, what level of accuracy do you expect to get from this test setup? (given resistor and meter tolerance). Is the same fixture used to test all drives, to ensure any error is consistent? I'm writing a short article about the different methods of power measurement, mostly from the persp...
