Hi @wsmolkowski,

thank you for reporting the issue.

I had a quick look into the AWS provider source code. The allowed range is specified here and a valid value is between 8 and 2048.
This is also mentioned in the providers resource documentation

In the AWS documentation I found a section that explains that the supported max value depends on the region:

Amazon FSx file systems provide up to 2 GB/s and 80,000 IOPS in all AWS Regions where Amazon FSx is available, and 12 GB/s of throughput and 400,000 IOPS in US East (N. Virginia), US West (Oregon), US East (Ohio), Europe (Ireland), Asia Pacific (Tokyo), and Asia Pacific (Singapore).

Hope that helps to understand the current situation.
