      Description

      It would be fantastic if we could store indexes on a separate disk, for instance an SSD, to mitigate the cost of fsync operations on non-contiguous pages in large datasets (think: indexes on arbitrary fields that are not incrementing, such as an email address). Working set for the index is less likely to be contiguous than for documents. In this situation fsync has a larger impact on performance.
