To me, that doesn't sound like a solution, only a workaround. I think the problem may eventually come back to bite you.

A WD user did some extensive testing to narrow down a slow write issue with a WD drive that passed all tests including DLG. Unfortunately he was not able to determine the root cause of the problem.
In your case I would confirm that the Samsung drive does not have a read problem.
