Unlike a hardware solution, if the controller card dies, you can forget about getting your data back since there is no "Standard" for RAID. On Linux you could just put the drives into another PC, as the meta-data for software RAID on Linux is not going to change across different versions of Linux.
RAID 10 should be faster than any individual drive for reads and writes, and it should also be faster than RAID 5.
Something is wrong here - either with the hardware or the tests.
