It doesn't help, when we're talking about Atlas probes. I have one probe, where
external flash died twice, even it's placed in datacenter with UPS-protected
power.

I know that a very small number of probes is not a valid basis for statistics,
but there wasn't a USB drive failure
Fwiw, I always power directly from an outlet, never tributary on the USB.
I've yet to have such fails, so my anecdata aligns with the underpower
theory.

It was powered through the dedicated wall plug included with the probe.

Could you perhaps write some statistical data regarding drive usage

I just had a Verbatim drive originally supplied with the probe go read-only, so
I would say RIPE is not procuring only SanDISK.

So I have a few theories. I have now had 3 different USB sticks fail on me:
Two Sandisk 4GB SDCZ33 and one cheap generic 8GB replacement.
The power draw of the TP-Link system + USB is probably more than the
opportunistic USB ports they get plugged in to. An underpowered probe runs
great MOST of th

Can you correlate tests-until-failure or data-written-until-failure?
One of mine has failed at least two times now, and it could be that

We have no clear idea why they fail. It seems that time to failure is
highly

No, the probe actually runs from the USB stick. The internal 4MB flash
is just enough to initialize the USB
+1. I lost most of the probes this way and I'm not really sure how to
recover them - I need to ask for a batch of USB drives or ask all the hosts
to remove them... can't this be handled better with a firmware replacement?
I would at least then ask all the hosts to unplug the USB and leave the
hosts
