Symptoms:

General RAID Card settings:

The two things that are most important on a RAID card is read and write cache. Both of these can be enabled or disabled based on how your system is configured. 

 

Read Cache: Always Enabled

Write Cache: Only enable this option if the server is on backup power (UPS/Generator) and you can ensure the server will never shutdown without user interaction. If this is enabled and a server loses power, there is a chance that the operating system and the SQL databases could be corrupt and unusable. Write caching will also make the I/O on your system increase.
