For RDS, the “trick” to getting max iops in gp2 cheaply is to get over 5334GB of storage, giving you the baseline of 16,000 iops (no burst at that level)[1].
This costs roughly $615 a month (double for multi az), way cheaper than io2 at that level.
It looks like 16000 provisioned iops in RDS is more like $2266 for 5334gb (double for multi az) a month. Varies by storage amount of course - 500gb storage is $1600 for single-az at 16k iops.
I’m not sure this change affects RDS storage pricing tho? The pricing calculator still calls Provisioned IOPs "IO1".

- jsmeaton 6y ago.. so it's cheaper to provision more disk and get free iops than to get a smaller disk and pay for provisioned iops? I recently bumped iops to 12k on one of my RDS instances, and I had to cringe when I did it.
