This is most likely a ridiculous question, but I’m intrigued by the thought so I’ll ask anyway. Is there any performance or benefit (outside of disaster recovery handling) of having a database on multiple filegroups stored on the same physical drive?
More specifically, if I create a secondary filegroup ONLY for full-text indexes on the same physical drive, is it beneficial? Could it be a bottleneck?
Log files in my situation are stored on a separate physical drive from data files.
It shouldn’t provide any additional benefit, except that with separate file groups you could, potentially, split out your backups. As far as the I/O on the same drive, you won’t gain much if anything by doing this, so if you’re considering it strictly for an I/O performance reason, I would suggest holding off until you can budget separate spindles.
