well, NFS may not scale to infinity, but easily beats this thing I guess... And for scaling to infinity: how about benchmarking vs. GPFS, BeeGFS or Gluster?

These are scalable but very expensive in the clouds.

They require a cluster of machines, the replicate the data across them, using either expensive EBS or local disk (a few larger instance to pick).

Maintaining them well is another burden. The cool idea of JuiceFS is to shift the maintenance to hosted Redis and S3.
