    Intel Z77 RAID 5 - EXTREMELY poor performance

    mediane

      I created a raid 5 with 3 hard drives Seagate 3TB ST3000DM001. I have top speeds of 10Mbs read and write...

       

      With the same controllerl I made a raid 0 with 2 SSD and performance is amazing. I made a raid 1 that works very well also with good speed. With a raid 5, speed is very slow ; it's a clue. Pool by window is only a little bit better but nothing as raid 0 or raid 1. There's no word to describe a such poor performance.

       

      All my hard drives work well, performance is pretty good, but nothing to do with raid 5. Result is really awfull !!!! I tried with SSD, same poor result.

       

      I need RAID 5 for security and speed purpose. But speed is not acceptable at all and I've no way to explain that poor result. For a few second, speed is fast but after, slow down and slow down and slow down...... It's unreal to me.

          Hello Mediane,

          Remember that RAID 5 array will verify and repair any errors on the raid structure, therefore a slow performance will be an expected behavior. However, could you please access the Ctrl+I menu and let me know check the Raid Status?

           

          Also, please copy-paste or attach the report generated within the Intel® Rapid Storage Technology:

           

          • Open the Intel Rapid Storage Technology user interface (Start » Programs » Intel » Intel® Rapid Storage Technology).
          • Click the Help icon.
          • Click the System Report icon.

            

          Let me know the model number of your system?

           

          Regards,
