Is there any sort of checksumming layer that could lie between the disk and ext3, or be implemented as part of ext3/4? We've just had a couple of drives recently where the drive started silently corrupting the data without generating any I/O or SMART errors. This is pretty disastrous as you don't necessarily find out about the corruption until it is too late. I imagine the overhead of such a layer wouldn't be that much. I would pay a few percent performance for knowing that the data is not corrupt.
