The May edition of TechNet Magazine is available on the web now and has the latest installment of my regular SQL Q&A column.
This month's topics are:
How to change the file locations for a user database
The difference between page latches and page I/O latches
Why database snapshots are not a good substitute for transaction log backups
Why I/O subsystem-caused corruption does not propagate to a database mirror
