AWS vs Azure vs Google vs IBM vs Oracle - VMs Q4 2024 - Block 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
For the sizes we selected, a base line 3,000 IOPS but Google and Oracle perform at a higher level of 25,000 IOPS approaching the nowadays standard of NVMe.
