Perhaps this is the comeback? http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO.html According to that, Linux can do Software RAID 0, 1, 4, 5, 10.. I glanced quickly at the MS KB regarding Dynamic Disk and it seems like it is simply RAID 0, 1, 5 so I am not sure what the difference is? I did a search on Google and found a benchmark on a software RAID 5 setup (11x120GB 5400RPM drives) using Promise Ultra66 controllers and a 1.6Ghz Pentium 4 processor and it had 93MB/sec read and 26MB/sec write.. Given the number of disks, the single processor and 5400RPM drives, that sounds pretty good to me.
