Does anyone know of a software implementation of RAID 10 that will work on a Windows Server 2008? Specifically I'd like to use it on a virtual instance running on Amazon's EC2, connected to EBS disks.

    What is the rationale behind a software RAID10 on a cloud instance? – Joel E Salas Feb 07 '12 at 19:09
  • I fail to see the reason for RAID-10 on EC2 using EBS disks? Your main concern is going to be data corruption and that'll still kill a RAID-10 volume. RAID-0 is technically just as 'secure' as RAID-10 if you want to span multiple EBS volumes on an EC2 instance. – Doug Feb 07 '12 at 21:36

    See http://blog.9minutesnooze.com/raid-10-ebs-data/ for my rationale on RAID 10. – Thom Feb 08 '12 at 04:35
  • Hmmm, not quite sure why my question was voted down. I did extensive research trying to find an answer before I asked it here. It was only when my research couldn't find a clear answer that I came here. If you'd care to clarify, I'd love to know so I might improve any future questions I ask here. Thanks. – Thom Feb 08 '12 at 06:54
  • @Thom I suggest quoting part of that article in your question. In particular, mentioning that it's already tested on Linux and now you want to apply it to Windows will give a better feel to the question. – Nic Feb 09 '12 at 17:59

Windows software RAID doesn't support RAID-10. I've never heard of third-party drivers for Windows software RAID and, frankly, I think I'd be afraid of them if they did exist. (They'd have to be debugged and battle-tested before I'd even think of using them...)

  • Thank you. (I agree that unless they had been around for awhile I wouldn't go near 'em). – Thom Feb 08 '12 at 04:36

There is no reason to create a RAID-10 configuration in the AWS environment. AWS is already providing disk redundancy in the EBS layer.

It can be worth creating a RAID-0 configuration. EBS is notoriously slow and striping your drive across multiple EBS volumes can significantly boost performance.
