Define the pipe!
You can now have EBS optimized EC2 instances with e.g. 500 or 1000 Mbit/sec throughput to EBS.
According to AWS a standard EBS volume will cope with 100 IOPS on average allowing some burts. As I mentioned before there was plenty of complaints and discussion about EBS performance workarounds though. Here is the news: AWS is offering provisioned IOPS EBS volumes. You can create up to 20 TB of provisioned IOPS volumes with a total of 10,000 IOPS per AWS account (but apply to extend your AWS account for more).
Seems like a lovely idea for a db data file, doesn’t it?
Does that make you run your EBS I/O benchmark again? Let me know about the results!
