ZeroFS vs. Amazon S3 Files: Choosing the Right Object Storage Filesystem

ZeroFS vs. Amazon S3 Files

I compare ZeroFS and Amazon S3 Files, two systems exposing POSIX filesystems over object storage. While S3 Files keeps a one-to-one mapping between files and S3 objects for direct API access, ZeroFS trades this visibility for compression, encryption, and flexible cloud support. The choice depends on whether you need standard S3 interoperability or optimized performance with a custom internal layout.

"The choice turns on the role of the bucket: if files must remain ordinary S3 objects, S3 Files preserves that identity; if the bucket can be an internal persistence layer, ZeroFS trades direct S3 access for packing, compression, and client-side encryption."
