Object Storage = Block Storage
+ Rich Metadata
- File hierarchy
Block Storage uses a filesystem to point where content is stored.
Object Storage uses a identifyer to point to content and his context.
This is my understanding of reading Content-addressed vs. location-addressed
Block Storage needs a filesystem and structuring so with bigger files sytems comes more overhead.
The Object storage has a lot of context about the file and doesn't need the file hierarchy.
The explanation on page 7 of the Dell paper clearly shows this..What troubled me to, was that on the scale of the hard disk itself it isn't explained.
I found that a Hard Disk itself always uses a Block storage mechanism (though that seems to be changing to)
