State of the art of European IaaS Compute - Q2 2022 - Local Storage IOPS
Go back to listSmall and medium Cloud providers tend to bundle their Virtual Machine with an extra volume made to store the operating system or extra data. This additionnal strorage can be either a part of of the local storage directly puggled to the hypervisor or a Block Storage given for free.
Despite the title of the section, all volume tested here are local and it's always explcitly written by the vendors. But the differenciation can be generally made by performance testing: Block Storages tend to have a maximum performance that we try to reach here and local storage easily burst at more than 80,000 IOPS.
To reach the maximum of the performance we use the same methodology that has been used for Block Storage IOPS :
- 4KB blocks
- Random access
- Read then Write
- Direct access to device without filesystems
- libaio engine
Cloud Mercato's assertions:
- Above 250,000 IOPS we have only DigitalOcean
- VEXXHOST is above than 200,000 IOPS for all categories of VMs
- Above 150,000 IOPS Vultr
- Linode, Nua.ge and gridscale also stand apart with more than 100,000 IOPS
