Thanks for headsup, I just checked this with cloudformation and it looks there's something wrong the way it estimates the billing savings. I am seeing below log messages
SC:2020-11-26T05:33:00 2020/11/26 05:33:33 autoscaling.go:247: ap-south-1 eks-worker-asg-dev Skipping group, license limit reached: would reach estimated monthly savings of $2643.70 when processing this group, above the $1000 evaluation limit
yeah suppose so. looks like you have to have a GP2 volume at least 170 GiB before it can burst above 128 MiB/s, and larger than 334 GiB before it'll do 250 MiB/s all the time.
