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! 

Is it possible to set the individual chip counts per serial and run all of these off a single cgminer instance?

Not sure if it has been started before or is hiding somewhere.

Which 780/780Ti do you have- Manufacturer & Version
Your hashrate
Your core clock / memory clock / +mV increase / bios version / temps / air or water cooled
What settings do you use for Cudaminer
How much power is drawn from your card / system


eVGA 780TI KPE
840-900kh/s
1253mhz core / 1750mhz memory / +0mV increase(bios already increases) / skyn3t bios / 40C / watercooled
cudaminer -H 1 -i 0 -m 1 -l T15x24 -o stratum+tcp://pool:port -u user -p pass
~300w from the card ~450w from system ~550w if -H 1 is enabled over -H 0 ( also an increase of 200khs )
