OVHcloud Metal Instances - IOPS
Go back to listI/O Per Seconds is one of the most used value to evaluate the performance of a volume, raw SSD, magnetic or Block Storage. The average and maximum IOPS gives a good preview of what will be the speed of a database or any disk-intensive task.
To measure IOPS, we use the well known tool Flexible I/O Tester (FIO) the following configuration:
- 4KB blocks
- Random access
- Read then Write
- Direct access to device without filesystems
- libaio engine

Cloud Mercato's assertions
Block storage and Local SSD are of course not directly comparable. The first one is a real Cloud service with its flexibility and ecosystem, when the second is a classical hardware provided to you.
As we can see, the physical device offer the best performance for OVHcloud:
- 650K IOPS in read
- 325K IOPS in write
