You will not attain a performance gain. > I said that in my blog post... but I was proven partially-wrong since: In many consolidated database environments, the redo from all databases go to the same volumes or (even more common) same spindles. In this case your sequential writes are no longer very sequential. At this point SSD has the usual advantage. Which is why consolidation platforms (Exadata, ODA) do well to place redo logs on SSD (and not just being silly like I originally thought) The price beats multiple RAID 1+0 volumes on separate sets of spindles (the old high performance redo option) too.
