Hi Ajay,

You've asked a pretty general question and not given a lot of details,
so it's hard to give a solid answer.

1. size

There are couches significantly larger than 1TB. The number of docs is
likely a more useful measure. Again there are DBs out there with
hundreds of millions of docs.

2. attachments

CouchDB "does" attachments, and can stream these to/from disk after
retrieving the necessary meta-data from disk. So assuming you are not
disk IO bound
your throughput will likely be limited by your HTTP connection anyway.

3. General:

I'm not familiar with the client libraries for .Net, can anybody else advise?

If you have some more specific figures and use cases in mind, perhaps
somebody can offer a more useful comparison. Things like  numbers &
size of doc, compatibility with JSON,  level of updates to docs,
relations between docs, redundancy & replication needs, working set
constraints, frequencies & types of queries you need all play a part.
