Even within the class 10 range they have improved from around 20mb/s to 45mb/s just in the last year or so. Write speeds are somewhat less. It is true that once the card is read at boot there are few writes to it but there are some and there are many reads.<br><br>The quality of a card does make a difference. Someone selling pre-configured cards is much more likely to want to pay $6 for a class 4 or 6 then $11 for a class 10. I can only say we have not personally had problems or had any reported problems with cards failures on the BBB or RPi2. I have no idea what people are using out there but from the beginning we recommended Sandisk class 10 8G or 16G cards.<br><br>When the Rpi first came out several years ago it was a great topic of discussion about SD card failures. At the time there were counterfeit knock-off cards being sold and lots of poor quality cards around. <br><br>My point is don't just use any card for the Allstar image. This is something you want to run reliably for a long time. Pay the $10-$15 for a good card.<br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><div><hr id="stopSpelling"></div> </div></body>
