microsd reliability issues

Post by fapedp » Mon Sep 17, 2018 12:13 pm

hello, in few mounths we have deployed about 35 raspberry pi3 wtware based thin clients.
at today we encountered some issues with microsd reliability because many time we found some pi "dead" and the problem was the microsd failure.
We have used some kingston and some sandisk cards, all sized at 16gb, all class 10.
All the time the problem comes out after a reboot of the thin client (example electric black out, software update, changed resolutions).

does anyone has some tip to resolve these frequent problems? maybe we need a particular microsd model? the actual stat is 6 failures on 35 thin clients deployed in about 3- 4 mounths wich is really too much.

also to foresee this issues, that as described comes out when terminal reboots for some reasons, should be very useful to be able to schedule a terminal reboot for example one time per week at random time/day.

Our fear is that terminal continue working with no warnings with the microsd failed, and this is dangerous because may generate mass failures on many terminals at the same time for exampe after an electric blackout. thank you in advice

My tip is: turn terminals off at night. 6 failures of 35 terminals in 3-4 months is really too much and we had no such experience before.

we are using the official raspberry pi3 kit wich doesn't have a power button, so doing what you suggest will cause users to power up the pi at the morning by unplug and plug the power connector which is really too tricky.

for now we will try to update to latest wtware version and we will try another microsd vendor like samsung....
