If there is nothing like this implemented in software in OpenBSD,
* If someone implemented it, would there be interest to actually include the patch in OpenBSD?
* Could a direct personal donation (separate from the normal donations to the OpenBSD project) to a developer be of use for making this happen, if so how big a donation, of what value would USD 1,000 be in proportion?
Not sure right now but next 12 months I could consider this, if you have any ideas about who feel free to respond or PM or anything you like.

This could be made in software with benefit, as a Softraid patch. So the frequently accessed stuff ends up cached on the SSD for faster read speed. ZFS on FreeBSD etc. does it in its "ARC"/"ARC2L" feature? There is some hardware solution, e.g. Intel made the http://ark.intel.com/products/70029/Intel-RAID-SSD-Cache-Controller-RCS25ZB040LX using the "Nytro MegaRAID" chip. Someone would need to port its driver to OpenBSD. Also in the past there was a "Adaptec MaxIQ". Those are the only two "Raid controller cache" hardware solutions I am aware of, do you know any more? (Was not sure if this belonged on tech@ or misc@, any clarification for me to never more crosspost please let me know)
