I'm little confused why people are being so weird with the OP, asking what the difference between a blob and a file aren't something for seaweedfs lol, Blobs and Files, and other terms are terms used to describe different layers of data allocation in almost every modern object storage solution.

Blobs are what lie under files, you can have a file split into multiple blobs spread across different drives, or different servers etc, and then can put it back together into a file when requested, thats how i understand it at a basic level

I think they are being weird. According to the facebook pdf they linked I think that would fall under chunks, but either way, why would someone advertise a filesystem for 'blob' storage when users don't interact with that? According to the paper 'blobs' are sent to append to files, but that isn't really 'blob storage', it's just giving a different name for an operation that's been done since the 70s - appending to a networked file. No one would say 'this filesystem can store all your file appends' and no one is storing discreet serialized data without a name and once you do that, you have a file.

They also seem like they are being vague and patronizing to avoid admitting that their product is not a unique filesystem, but just something to distribute XFS.
