Dropbox's fixed storage for a fixed price business model probably assumes a large majority of their customers wont use the full 1TB they pay for. Providing smaller amounts of storage for a lesser price would just reduce revenue without reducing storage costs, so it doesn't make sense for them.

If you want a pay per GB service, setup a S3 account (or similar) and get one of the many decent frontends to it. Its what I do.

Have you found decent frontends which let you sync files between Windows, Linux, Mac, Android, and iPhone, using S3 as the backend? If so, I'd love a few pointers, because I've been looking for something like that.

Sounds like you want Dropbox.

My personal use case involves files stored on a NAS, which is accessible via VPN and any client with a file browser (so, basically every platform). NAS is backed up via rclone to cloud storage. Its not sync, but I dont really want files synced to all my devices.

Possible business opportunity here?

I think $10 for a windows/mac/linux desktop app, $5 for a android/Ios version. (Maybe get all versions for $20)

You drop in an S3 or Azure storage key, it lists the files, create containers, lets you upload/download to whatever device you are on at the time.

Not necessarily a dropbox killer since you'd have to have a cloud storage account and no how to use it, but it would definitely serve a certain niche.

For Mac, Transmit app works pretty well for me. Their transmit iOS app was good also but sadly discontinued.
