Haha! Thanks man. I didn't know 'Industrial' SD cards existed. I'll be sure to look for one.

Usually industrial SD cards are SLC, not MLC. And $85 can be the price for 1 card, not 10.

$85 for the 10 pack.
$44 for the 5 pack.

I've had various Pi's over the last few years with various SD & uSD cards from cheap noname brands to more expensive brand names 4GB - 128GB.

I've never had a card fail me in the Pi yet, in fact the only failure I recall was a noname 8GB card and that failed in my mobile. I could be lucky but I'm talking about at least 9 Pi's and well over 2 dozen cards.

Swissbit industrial cards do not work. We never figured out why, and Swissbit were not really interested in helping.

jamesh,
2500 devices, very few corruptions. How is that 'lucky',...
I don't like to speak of "luck", I will leave that to fortune tellers and those that play fruit machines.

Statistically if the failure rate is only a "few" in 2500 then liamkennedy's anecdote is is to be expected.
Yes, very infrequently, an SD card dies. Not caused by a HW failure on the part of the Pi, but simply because sometimes stuff just dies, though bad use, or just maybe it was destiny.
I don't like to speak of "destiny". Again I will leave that to fortune tellers.

Stuff does indeed fail. There is a steady trickle of people with unformattable SD card issues coming by here all the time.

Is it significant given the number of Pi sales? I have no idea. But for sure it exists.
It really is as simple as that.
As simple as what? "Luck", "Destiny"?

I think we agree though. The Pi is fine. As were all those computers that had to deal with the unreliability of 3.5 inch floppy disks.
SD cards should be used with that in mind.

I had problems with SD corruption only in my early days of Pi tinkering (Pi1 model B). Most of my problems were related to two things:
  • Bad power source (Get a good powered USB hub with a 2.5A+ adapter)
  • Improper shutdowns (use SSH to log in remotely and run 'sudo shutdown')
If you attach the SD card to another system for any reason always unmount/eject the card before removing it. Depending on the OS and settings this may or may not be required, but it's a safer habit to get into.

SD cards can also be overused into oblivion. Excessive disk activity can take a toll on them.

You can't boot from a USB hard drive with Older Pi models < Pi 3, however you can boot from a SD card and keep your root file system on a USB hard drive. I had my first Pi model B running like this using a cheap 40GB (yes it was that old and small) USB HDD. It ran flawlessly for 4+ years as an ADSB receiver and would have continued if I didn't replace it with a Pi 3. It seems vital to use a good powered USB hub for this, don't plug the HDD directly into the Pi.

One more piece of advice is make backups of your SD cards when you have everything working the way you like. Create your own .img file.

I destroyed a couple of SD-cards and USB flash drives with my Pi’s, not just corrupted but really destroyed. I was running MySQL (lots of read/writes). Never occured to me to blame the foundation since a bit of Googling learned me that SD-cards & USB flash drives don’t like a lot of writes. Switched to USB HDD’s, havent had a problem since.

I don’t get how topicstarter (a system administrator) could’ve overseen this :? But hey, as long as you get it to work in the end we’re all happy 8-)

As suggested by PM, we've really done this to death.

In answer to the original question, never. Because the Pi doesn't destroy SD cards, as shown by the plethora of posts on here.

So, closing.
