    All HDDs and all SSDs can be used in RAID.  The only reason some drives are "recommended" for RAID when others aren't recommended has to do with their ability to handle vibration.   They assume you'll be putting a bunch of them into an enclosure or rack together where the vibration might build up.  That and you should never use Green drives in a RAID as the power saving functions can cause chaos.  For a two drive array vibration is really a moot point.

    There's no reason not to use a couple Velociraptors in RAID, but unless you use an actual hardware controller there's also not going to be much benefit.  Honestly you'd be 100x better off just investing the money into a good SSD.

    As to doing a RAID of SSDs you're unlikely to see much benefit to a RAID 0 or RAID 5 as far as speed is concerned.  Most likely the extra latency the controller would negate any benefit of the RAID.  It might even end up slower than a single SSD in some cases.  RAID 1 is good for redundancy in case one fails (however you still need a backup in case of logical corruption), so if uptime is important you might consider that.

    JaredDM: Western Digital (WD) tech support told me the timing circuits within the Velocity HD's are not suited for RAID because one will drop out and require rebuilding the array due to one being out of time with the other.  That is the explaination they provided.  They said only their RED Label WD HDD's are RAID Certified and only they are accurate timing circuit wise to work in harmony together for RAID.

    To answer another members question, the RAID is supported by the AMD 990FX Chipset on the Gigabyte Motherboard.  I would have quite a time finding another one of these boards since everyone is out of stock of this motherboard.  Since there is problems should a motherboard fail because the Chipset is tied to the RAID functionality, they you are saying if I ever do consider RAID, I should use one of those RAID Controller Boards that insert into one of the slots on the motherboard, just in case I should suffer a MB failure.  I take it your implying, should I suffer a MB failure and I have an external RAID Card that can be removed from the MB and inserted into a different MB with a different chipset, then I would not lose my RAID Array and the information on the HDD's, and I would be able to use the RAID Controller Card and the RAID Configured HDD's in a new MB?

    If it's software RAID, you're all good. The hardware will see the drives as individuals. I've seen Raptors used in softraid before.

    Assuming it isn't software RAID, what controller are you using?

    I do not know the difference between software and hardware RAID.  I can tell you the Motherboard has raid capability I believe.  The motherboard is a Gigabyte 990FXA-UD7 Ultra Durable 3.  On the web page: [] it says, " AMD SB950 provides 6 native SATA3 ports with super-fast 6Gbps link speed and RAID 0, 1, 5, 10 support".  I have given the link so you can see the complete description of my motherboard.  The manual for the motherboard is still packed away in boxes somewhere in many unpacked boxes back when I moved.  However, I was able to locate the motherboard box which is how I got the model of the AMD Platform Motherboard.  Basically, I have a FX-8150 3.6GHz 8-core Black Edition Unlocked Processor and 32GB of Corsair Dominator RAM.  The RAM is 4 sticks of 8GB's each and is a speed matched set of 4.  The 2 new SSD Drives I have are Intel 520 Series 120GB drives which I have in addition to the 3 WD Velocity Raptor 10,000rmp hard drives that I have to use in my build.  The Operating System is Windows 7 64-bit Ultimate Full Version.  I do not know if the OS has any bearing on if RAID is supported or not, that is why I provided that bit of information for you.  If you need more information to fully answer my original question, please let me know.  Thank you.

  3. I have 3 identical brand new WD Velocity Raptor 10,000 rpm HD's that I bought for use in a newly built high end tower computer, and I would like to experiment with RAID.  The WD Support told me that these drives can not be used for RAID because they are not strict enough on the speed sync or something like that, and one will eventually drop out.  They tried to sell me the red label drives that cost well over $250 each that is certified for use with RAID.  I am reading conflicting articles that mention using the WD Velocity Raptor HD's.

    My 1st question is: "Can these WD Velocity Raptor 10,000 RPM hard drives be used reliably in a RAID Configuration such as RAID 0 or RAID1 or RAID 5?"

    I also have 2 identical brand new smaller capacity SSD drives.  Without looking, I believe they were Intel SSD's.  I bought all of this equipment about 4 years ago and I am just getting it out of storage since I moved during my PC build project.

    My 2nd question is"Can I use these SSD's in RAID 0, Raid 1, or Raid 5 reliably or does it require special SSD Drives?"  I am mainly interested in speed and might be interested in redundancy if it does not affect performance greatly, depending on the trade-off considerations.  Although I am well experienced in PC maintenance, I am new to building a RAID array.

    Thank you for replying to my questions.
