Hi Vincent, have you already tried the more common tuning operations like row cache?
I haven't done any disk level caching like this (we use SSD's exclusively), but you may see some benefit from putting your commitlog on a separate conventional HDD if you haven't tried this already. This may push your read/write pattern to do more sequential access.
