… I was decided to test it in strict_sync mode. As I understand FusionIO in default mode, like Intel SSD, is “lying” to… internal memory, not to final media. And FusionIO has “strict_sync” mode to guarantee fsync is trustworthy. So let’s benchmark it… really loose transactions in case of power outage in default mode, this is something to check.

Thanks Roland, Indeed this applies to standard behavior. If you get to Strict mode it is going to be changed… but a lot of other stuff is going to change as well. In most cases I’ve seen enabling strict mode also needed a lot of minor fixes to the application to make it work
