What is the maximum length of an Azure blob name

On Azure itself, I find I can make blobs with names of length 1000, but not 1100 (so I guess 1024). Using dev storage I can do 200, but not 300 (so I guess something related to MAX_PATH). Is there an official limit?

From http://msdn.microsoft.com/en-us/library/dd135715.aspx:

A blob name can contain any combination of characters, but reserved URL characters must be properly escaped. A blob name must be at least one character long and cannot be more than 1,024 characters long.

The Azure Storage emulator supports blob names up to 256 characters long.

Looking at the schema of "Blob" table in development storage database, the "BlobName" column is nvarchar(256) so I guess the limit is 256 characters for blob name in development storage.
