If the disk is SSD, is there any performance difference between file and device storage?

Yes, when Aerospike is using it as a raw device there is no filesystem overhead and Aerospike have also been optimized for SSDs so you will see better performance when using it as a raw device. See this about Aerospike and flash storage [Flash Storage | Aerospike Documentation](http://www.aerospike.com/docs/operations/plan/ssd/)
