- vcz_fr 6y agoThis is correct, according to the documentation [^1]. I could not find any explanation of the differences between io1 and io2 that would justify the increase in IOPS per GiB and durability on the EC2 user guide [^2] or on Amazon Builders Library [^3], though. Note that 64k is the maximum IOPS per volume, not per instance the volume is attached to. Therefore you can use software RAID configurations to increase your performance or fault tolerance further [^4] Links: [^1]: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volu...
