And explain why it is relevant. Even mainstream NAS devices with even dozens of disks (I believe) use software RAID.
As far as I understand, any raid is software driven (any computer hardware is software driven :-). All is to know where the software is run. * Hardware raid is a box (nas) or a card (scsi) with on board software and processor(s) I don't have to care with. I had one, very handy! Usually pretty expensive and you have value for the money. * fake raid are build in your own computer. Depending of the make, part of the software is in rom (possibly in the bios), part in the OS that may have to be windows (and what version?) to use the maker's driver. Linux may or may not see this, probably not. * soft raid in linux is a very well implemented software, kernel module + user space commands. Of course it uses processor power, but who needs really all the time our processor power? I guess the penalty is little. But I have no idea of how windows manage this, probably not that well. That said, I have no continuous availability necessity in my use, so I find raid a waste or data space and no more use it... good discussion, anyway, but don't seems to show any new development about raid thanks jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
