I'm surprised at this, especially if the commit Will bisected it to [1] is the culprit. That is a change in generic ide code and could thus very well affect other users too. This is a clear regression and IMHO, if it is confirmed that that commit is the cause of the regression, it should be fixed. And if not, it could still be worthwhile to track down which commit is the cause. As for the lack of other reports, that could very well simply be because: 1) there are not that many users of IDE drivers anymore 2) most users don't really consciously watch their disk speed As long as the IDE code is in mainline, I don't see why regressions should be ignored. Adding the ide list and David to CC for other opinions.
