On thing to remember is is that the parity is for specific pieces of file system data. So not your entire dataset is at risk when only write errors occur on a few places on a few disks, only file system objects that have data stored in those places are at immediate risk. This means that only files unlucky enough to have multiple failing sectors for the same stripe width to be really impacted. Of course this only matters as long as we're talking about bad sectors and not full disk failure.
