What are the pros/cons of separating IN_ROW_DATA data and LOB_DATA in different filegroups? (MSSQL 2K5 EE SP3 CU10 x64)

It really depends on the system. If you store a lot of LOB data and you can seperate this to a different drive and/or controller, you'll see a performance benefit. Also, it means you can backup that filegroup seperately from the others in the event you're looking at extremely large sets of data. The only con is the added overhead of maintaining additional drives and the extra work required when restoring the database because of the extra drives. In short, it can basically be all positive. In general, I consider it a best practice to seperate that type of storage into another file group.
