I have a terrible setup. But first, let me say that I used a voltage meter to get a reading from my outlet, and it was starting at 119.5 volts right off the batt, with nothing plugged in.
I am running a lot of things off of two household outlets, most likely rated at 15 amps on one circuit:
- My Mac Pro (2012)
- Two monitors
- A halogen desk lamp
- A small pair of crappy speakers
- 9 (nine) external hard drives, including a 4-bay RAID solution.
The last bit is what worries me. 8 of the hard drives are all daisy chained together, using FW800. I have a power strip with them on it plugged into my power strip in the wall (a fire hazard...). When everything above ^ was powered on and running, my line voltage dropped to 118.
To be specific, I am trying to copy large video files from these 8 drives, over to the RAID When the copy started, it stopped halfway through (24 hours later), and one of my drives had been "disconnected improperly" or "removed without being ejected." I tried starting the copy over and this time it failed even sooner, with all the drives ejected "improperly." It could be a software bug, but I suspect it was hardware/power related, e.g. drives are underpowered and are intermittently shutting off, or one of them has very corrupt data on it. But that is another issue entirely.
My main concern is: is 118 volts not a good sign when powering this many devices at home on one circuit?
