Jose, I respectfully disagree. RAID 0+1 is a mirrored array with segments that are RAID 0 arrays. RAID 0+1 has the same level of fault tolerance as RAID 5. If a single drive fails, the array becomes effectively a RAID 0 array.
RAID 10, on the other hand, is an available standard on many Enterprise controllers. It is implemented as a striped array who's segments are always RAID 1 arrays. RAID 10 has the same fault tolerance as RAID 1, and carries the same overhead as mirroring alone. It has a huge I/O gain in that all segments are RAID 1 stripes.

If I recall, Adaptec and Dell coined the the Raid 10 term back in 1999. I always use the bios utility to create my drive raid arrays, what does that say?

I'm using the web array config utlilty from hp to do this. It offers to create a raid 0+1 array but when i do, it turns out to be just raid 1(thats what it says in the bios bot up screen) also, i have another array with 2 drives which the utility offers to make raid 0+1 which is impossible with 2 drives. but if you say "ok", it happily goes on to do this(of course, it only turns out to be raid 1 as well) has anyone else had this issue or am i doing something wrong? Also, it never seems to have an option for raid 10. does smart array support this? thanks List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
