In my survey this week I'd like to find out how large the largest single SQL Server database is at your company (how much space does the data take up on disk, roughly). I ran a similar survey almost two years ago and I think it will be interesting to compare the results.
[Edit: the survey is closed now.]
I'll report on the results next week. If you answer with a database size more than 20TB, I'd be really interested to know the size so I can tell people – completely anonymously of course. Leave a comment if you want.
PS Don't forget the early-bird registration for our March performance tuning class in Dallas ends this Friday!
