Ephemeral storage capacity

[premun]

The .NET team is looking into using Azure Container Apps for a service that will need to work with ~100GB worth of git repositories on a local storage. This storage would ideally be ephemeral and private to a replica so not shared.

I read the documentation and I have these questions:

1. I understand that the only way to get 100 GB is to connect an Azure Files account?
2. Will the git operations that require low disk latency and access the disk very frequently work well with the Azure Files mount?
3. Will I pay extra for mirroring of the changes back to the storage account? (I do not need or want this though)
4. I've also noticed this issue - Increase ephemeral storage for containers #599 - but I understand this already happened and the increases are the 8 GB max?

Thanks!

I tried to run the service with git repos checked out onto an Azure Files mount but the operations were very slow. I tried different storage account types too. I also tried a premium storage account via NFS but it still wasn't able to clone one of our larger repos (/~https://github.com/dotnet/runtime) onto file share.

I've also checked custom workload profile but there's no option to add storage neither.

Other than that, the tooling, dev experience and other aspects of Azure App Containers are awesome but not having enough storage is a deal break for us :(
