The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Enabling NCQ on alreay use harddisk (RAID 5)

Asked by zacker69 in Computer Hard Drives, Computer Servers, Hard Drives & Storage

Hi,

I just want to know if I can enable NCQ on harddisk that is already used. I have harddisk and controler that support NCQ and I want to check if it will give more speed but I want to be sure that it is not dangerous for the data to enable it while data is on the disk. I have 4 disk configure with RAID 5. Is it dangerous? Does I need to format  the drive to use NCQ? Does somebody try it with raid 5 and saw more performance?

Thank you!

Dany
