I hope everyone is having a good time gearing up for the holidays.   Throwback Thursday is a bi-weekly blog series where I dig deep into my evernote collection and find some great content on a single subject and share it with you.  In the third installment of the Throwback Thursday series we are going to cover some helpful SQL Server disk articles.

Measuring Disk Latency with Windows Performance Monitor –  Perfmon (Windows Performance Monitor) is the gold standard for measuring disk performance inside of windows.

It also has tons of links for great additional reading on how SQL Server works with disks. For example, Bob’s write up on SQL 2000 I/O basics is still relevant today.
