Can any of you fellow Raspberry Pi owners recommend SD cards that just don't poop out during use?

I found it strange a few of mine gave me errors while others didn't.

Example:
[2014-07-28 22:28:46] LIR2: Comms error (rerr=-4 amt=0)
 [2014-07-28 22:28:46] LIR1: Comms error (rerr=-4 amt=0)
 [2014-07-28 22:28:46] LIR0: Comms error (werr=-4 amt=32)
 [2014-07-28 22:28:46] LIR3: Comms error (rerr=-4 amt=0)
 [2014-07-28 22:28:46] LIR 2 failure, disabling!
 [2014-07-28 22:28:46] LIR 3 failure, disabling!
 [2014-07-28 22:28:46] LIR 0 failure, disabling!
 [2014-07-28 22:28:46] LIR 1 failure, disabling!


I know it is not the hub because one brand of SD card handled the cgminer for multiple days without ever having comms error. However, this was the V-Data sd card that comes with the raspberry pi bundle on amazon.

Need, good, SD card! Help!  Grin

Anyone of these ( http://cryptofarm.net/product-category/sd-cards/ ) work fine. Never had problems.

Thanks for posting.

Unfortunately I bought those kingston in store and I had to return it. It's just strange how one brand SD with same OS can work 100% and another SD with same os is 75% as efficient :/

You would expect a SanDisk SD to be better than a V-Data SD

It could be a problem related to that specific sdcard. SanDisks are also reliable. But you know.. sometimes is just bad luck.

Disable logging, try make everything ReadOnly on the SD. Make a ramdisk and log the stuff you need there. Make some shell scripts to save all the logs at once before you shut down.

I use sandisk class 10. Solid.
I also have watchdogd running to ensure continues operation.

Or, compile cgminer with low mem usage option and manage it remotely - you could run in memory and don't write anything onto sdcard - that would minimize the risk of file system damage
