Is that a use case they are really targeting though? Their splash page mentions big data with model generation and genomic sequencing as examples. I can really only speak to genetic sequencing. The IO pattern for these workflows is almost all streaming reads/writes. Random access takes too long when you are reading/writing 100-500GB files.

Postgres doesn’t like running on NFS either to be fair.

postgres + rocks fdw would be a more interesting test case (or any LSM DB)
