Thanks for the suggestion but the performance was terrible when write
cache was disabled.
Performance degradation is expected. But the point is - did the
anomaly, that you have pointed out, go away? Because if it did, then
it is the disk cache which is causing the issue, and you will have to
live with it. Else you will have to look elsewhere.
