Probably not. The DL740 is pretty old.

While a single stream 50MB/s wouldn't be a problem it's could be
different with 6 stream and the same overall bandwidth.
But if I interpret the DL740 specifications correctly the 6 PCI slots
use 3 busses.

If you're using mythtv trunk it might be better to use the discs
If the network storage works better than the internal controller I would
suspects a driver or hardware problem.
