    6X Raptors overkill?

    For an extreme gaming rig with 8 gigz of RAM and dual 8800 Ultras,would RAIDing 6 raptors be overkill or good for this type of rig?Im thinking 4 would be enough but since this is gonna be the highest line gaming rig why not all 6?

    You want Raptors instead of 15K RPM SAS drives?

    Re: 6X Raptors overkill?

    You'd have to use an add-on PCI controller card to do that, and then you'll be saddled with the real-world limitation of ~ 100 MB/sec throughput no matter how many drives, so it really isn't worth it, IMO. SCSI drives don't always do better than raptors in desktop systems anyway, they're optimized for all-out server duty, not gaming. If you don't mind the added risk of data loss imparted by RAID-0 then use a pair of the ADFD models on the on-board RAID controller and you might gain more. How much depends on several variables...

    Re: 6X Raptors overkill?

    The motherboard would be one of those expensive Asus Crosshair mobos http://www.newegg.com/Product/Produc...82E16813131593 probably the most expensive socket AM2 mobo out there.
    And it has 6 SATA ports,wouldnt I be able to RAID 6 raptors with that?
    I know an onboard RAID controller wouldnt be as good as a PCI add on,but still,wouldnt it suffice?
    If not then how many raptors would be good?2 maybe 4?

    Btw no Im not worried about data loss,which Is why I want RAID 0,if I were worried about data loss I would do RAID 1,but thats for the buisness/office rigs,not for a gaming rig

    You'll have to study the owners manual to see how many drives it'll support in a single array.

    The onboard RAID controllers, depending on whether or not they're on the PCI bus, will outperform a PCI add-on controller. The advantage that a PCI card would have is that it will probably eat up a bit less CPU time.

    Given the limits of the controllers and drives, I would stick with a two drive array.

    Hmm,see I learn something new everyday here almost lol
    I had no idea that a RAID array could be limited like that,I thought you could RAID as many drives as you want as long as you had enough SATA ports.
    Will check manual now to see if it has a limit

    So you are saying that the onboard RAID controller on my Asus PC-DL will outperform something like this?

    Re: 6X Raptors overkill?

    Hmm Im looking at manual right now for this mobo and cant seem to find anything about RAID 0 array being limited.It simply says 2 identicle drives for RAID 0 or RAID 1
    Raid 0+1 or 5 or 10 on the other hand say need at least 3 or 4 identicle drives
    And that it has 2 RAID controllers,one is nvidia nforce southbridge and the other silicon image.
    Why would it have 2 RAID controllers I dont get it

    Re: 6X Raptors overkill?

    There are people that use two separate RAID arrays, not really unusual. Striping for O/S and apps, mirror for simple storage. The SIL controller is the one to use for a mirror. I know nothing about nvidia boards/chipsets so lets get some nvidia fans in on this.

    Re: 6X Raptors overkill?

    Given the limitations of SATA-1, I think 3 Raptors in one RAID-0 array would be the practical limit. That's going to be fast enough to make your head spin on sustained transfers.

    The reason that many boards have 2 separate controllers is that 4 is the limit for the chipset controller, and they want to add more ports.

    You might consider using the 2nd controller (SIL) to create another RAID-0 array and actually install the games on that, leaving the main array for OS, swap file and even put some of the game files, like terrain, on the main array. The potential is there for boosting performance.

    Re: 6X Raptors overkill?

    Ok lets see if I understood this.
    NVRAID controller would be for 4 drives max and the silicon image for 2?

    Re: 6X Raptors overkill?

    You should be able to run 4x Raptor in RAID0 with NVRaid controller and that will give you an extremely high sustained transfer rate (good for copying large files and loading big scenes in games).

    nforce590 offers 6 SATA-2 ports natively but doesn't support a single array involving all 6 ports. This is probably to cut down the complexity of the chipset logics. If you absolutely want a RAID0 array with 6 drives, you will need a third party true hardware RAID controller. These controllers are expensive (probably twice the price of your mobo) and usually designed for server environments. You will need RAID5, RAID6 or RAID51 in order to fully utilize their power. Also they only come in PCI-E 4x/8x or PCI-X form, so make sure your mobo has one of those slots.

    Re: 6X Raptors overkill?

    No I dont absolutly need 6 raptors which is why im asking just to see if its posible.
    If 4 is the limit then ok fine by me,thats more then enough for any hardcore extreme gaming machine

    2 Raptors in RAID0 on a PCI-E add-in controller with its own cpu and onboard cache would be the quickest IMO at a fairly sensible price(around $600 ). You just will not utilize the higher STR of more than 2 drives for gaming. This setup still won't be much quicker than a single drive.
