With new updates of FusionIO drivers I was able to test it on our Dell … to test it in strict_sync mode. As I understand FusionIO in default mode, like Intel SSD, is “lying” to application… commit only to internal memory, not to final media. And FusionIO has “strict_sync” mode to guarantee fsync is trustworthy. So…

… comparison is to compare results with FusionIO 320GB MLC card, so I will copy results from FusionIO 320GB MLC benchmarks. For benchmarks… reached enough level of reliability yet (see comments to post FusionIO 320GB MLC benchmarks), however I put results here to show…. I think it is competitive vs FusionIO if we look into price/performance analysis (remember FusionIO is twice as expensive) Random writes…

… Dell PowerEdge R900 server with 32GB of RAM and with FusionIO 320GB MLC card, and run tpcc-mysql benchmark with 500W… cause of such difference ? I am not really sure. Apparently FusionIO driver is sensitive to IO block size. And I know… something is going on inside FusionIO driver, but this is topic for another research. For history, FusionIO card information is Found 1…
