SD Class 4. = 4MBps and Class 6. = 6MBps.

They say on the Internet Class 4. and 6. are good for Recording Hight Definition Video.

 

Then they say Class 10 = 10 MBps and it is good for FULL Hight Definition Video.

 

So why do they say Class 4. and 6. are good for High Def but Class 10 is good for Full HD  what is FULL HD    is this not High Def?

I would not bother with anything less than class 10. There are additional classes past 10 of u1,u2, and u3.

In fact I just purchase a 32GB class 10 u3 micro SD card during Staples Black Friday sale for $10

They are probably referring to 720 (1280 x 720) as high definition & 1080 (1920 x 1080) as full HD

 

As above - just go with class 10 or better
