Storage capacity of MSMQ on Windows 7

Is there a storage limit for MSMQ on Windows 7? I read that for versions older than 3.0, there is a 8GB limit. But again 开发者_如何转开发in a white paper read

MSMQ 3.0 message storage is now limited only by disk space. In particular, MSMQ 3.0 has relaxed the 2 gigabyte (GB) storage limit per machine. The theoretical capacity limit for persistent MSMQ 3.0 messages is now 1 terabyte (TB).

Any input/pointers?

There's not really a storage limit for MSMQ, because MSMQ is a messaging service, not a data-storage service (a.k.a. a "database"). Here's an excellent article on the subject:

The summary is: if you're asking about the storage limits of MSMQ, you're probably not using MSMQ correctly.
