One of the reason we dislike RAIDs is that there's nearly always some faffing around trying to work it out. Unfortunately there are around a dozen variables that can be tweaked and very few arrays even bother to store their configuation information on the disks. The only ones that might do are the ones where you can adjust the settings which is generally the more expensive ones. Another possible issue with SATA that I'm not too keen on is that the RAIDing might not be done in hardware. It could be the driver that performs the RAIDing and pretends to its client that it's a single device. That's a cheap solution that wastes CPU time and probably set you up for problems in the future. -- Andrue Cope [TeamB] [Bicester, Uk] http://info.borland.com/newsgroups/guide.html
