Do you need SSD?

George Crump @ Storage Switzerland has a great post on evaluatiing whether or not SSDs make sense for your IT environment.

The steps to figuring out if you are a good candidate?

  1. Gather statistics about your environment: storage I/O, application server performance
  2. Figure out your CPU utilization — to help you determine if your problem is the application stack or the storage
  3. Delve deeper to find out if storage I/O is the problem:  can you figure out is the disk queuing commands, and there is a backlog?
  4. Can you improve response time with more drives?

Answer these questions, and you should be able to figure out if you can take advantage of SSD.   Read the full article for more advice on what you should look for in these tests.
