Jim Donahoe shows how to use the temporary SSD on an Azure VM for SQL Server’s tempdb:
Remember, this disk is as the title of this section says…TEMPORARY! Do NOT put ANYTHING on this drive you cannot afford to lose. Don’t say nobody warned you either, because the drive itself contains a nice little txt file warning you, here is the EXACT text:
WARNING : THIS IS A TEMPORARY DISK.
Any data stored on this drive is SUBJECT TO LOSS and THERE IS NO WAY TO RECOVER IT.
Please do not use this disk for storing any personal or application data.
It’s good to see what you need to do to get this working. I’ve found it just to be easier to set up a permanent SSD, but if you’re on a tight budget, this can save you some cash.
