We are running on I3s since they came out. NVMe SSDs are really fast and I managed to push them to 75k IOPs. As Bhuvan mentioned the i3 storage is ephemeral. If you can work around it and plan for failure recovery you are good to go. I ran Cassandra on m4s before and had no problems with EBS

i3 instances will undoubtedly give you more meat for buck - easily 40K+ iops whereas on the other hand EBS maxes out at 20K PIOPS which is highly expensive (at times they can cost you significantly more than cost of instance). But they have ephemeral local storage and data is lost once instance is
