    Questions about RT3WB080 PCI-Express x8 Low Profile SATA III (6.0Gb/s) RAID Card

      Hey everyone, I wanted to see if anyone has any experience with this card and specifically its raid 5 performance.  Some of these cards look great on paper but once you throw 5-8 hard drives in there and set up Raid 5, reads /writes go through the floor.

       

      Here are some of the specs for the card:

       

      8 x SATA 6.0Gb/s

       

      RAID:

      RAID 1/5/6/10/50/60

      Cache Memory:

      256MB

      Features:

      Supports data redundancy LSI SAS2108 ROC technology True MD2 form factor for low-profile height and half length adapter slots Includes a connector for optional hardware-based keys that easily plug in to unlock advanced software algorithms designed to improve performance and enhance data protection

      Here is a link to the page on the Intel site:

      I will be installing it in a workstation in a 16x PCI-e slot. (not rack mounted, so I don't require the low profile component, I'm hoping they include the larger metal piece in the back for a normal sized slot.)   So, has anyone had any experience with this card?  Is there anything I need to watch out for before buying this card?  Does it fully support the speed of Sata III as advertised?  My biggest concern is that the performance will take a nose dive when I configure it as raid 5.  This has happened to me before with other "highpoint" cards, etc. I figure if I want the best performance I need to get the best card.

       

       

      Any advice will be greatly appreciated.  Also, if there is a different card that may work better for me, feel free to recommend it.

       

      Thanks in advance!

       

      Carl
