At the recent SQLSaturday #28 in Baton Rouge, LA, I had the opportunity to meet Wes Brown (Blog | Twitter), and attend his session on “Understanding Storage Systems and SQL Server”. I enjoyed his presentation and also discovered that Wes has a blog where he shares his deep knowledge of SQL Server I/O. If you are interested in learning more about SQL Server I/O, his blog offers useful posts, presentations, and some software tools he has written for himself. For example, he has a Disk Drive RAID Configuration Tool that you can use to help give you an idea of RAID performance based on drive characteristics and other factors.
