I got an error last week from a new raid6 array about a mismatch_cnt.  I 
did some reading online, performed a repair action on the array, 
performed a check action, and checked for the mismatch_cnt again.  The 
number was greatly reduced, but it was still there.  According to mdadm, 
everything appears to be working fine.  All the drives are passing short 
tests on smartctl.

What is mismatch_cnt really?  Should I even be concerned about this?  
The array is giving me 25-30MB/sec performance on an sshfs mount over 
the network.  With a local copy I can see speeds of 50 to 60MB/sec.

Hello,

What kind of SATA cards/controllers do you use?
