How can you do a software RAID 10? I have 4 HDD and I already did RAID 1 (created 2 mirrored sets). Now I need to RAID 0 the mirrored sets. I am using windows server 2008 standard software raid

RAID 10 is not available as a software RAID level. To be honest you really should be using hardware instead anyways. Software RAID levels available are 0, 1 and 5.

Yea, I am stuck with a software RAID for now. No way to get hardware RAID setup in the meantime.. I guess I will just stick with a RAID 1 Thanks

you could create a striped set (raid 0), then mirror it (raid 1). now you have raid 10. you could research more on that.
