How much storage does provide?

I am seeing pricing options.

It provides about CPU, ram, and price but not how much SSD or NVME it provides.
Also, I know the free tier includes 160gb bandwidth but how it will be extended once I start paying? unlimited bandwidth?

VMs have 5GB disks for temporary storage. This goes away between deploys or when they reboot, for persistent storage you can add volumes with fly volumes create.

Once you surpass 160GB of bandwidth, we bill a small amount per GB. You can use as much as you want!
