Google doesn't charge for IOPS either, but they do explain how things are limited. For example, speed in MB/s is limited by the instance size so that you don't use the entire network link for your connection to the disk. IOPS are limited by the size of the disk. If you're sharing the disk with other people, you're going to be limited in your IOPS. For example, if you get 10GB of SSD storage, you'll get 300 random IOPS, but another user with 50GB of storage will get 1,500 IOPS because they're renting a larger portion of the disk. If DigitalOcean isn't doing something limiting, they'll have to in order to prevent the situation that you're describing. You don't have to charge for it in order to prevent bad neighbors. https://cloud.google.com/compute/docs/disks/performance https://cloud.google.com/compute/docs/disks/performance
