I have used a 12-way SAS RAID controller as dumb controller with software-RAID and have gotten better results. But that was one with Linux support that sucked. With good Linux support, that may be entirely different. On the exotic, I agree that in enterprise environments HW controllers are the norm, but I think by now that is mainly because they are simpler to use. > And for some strange reasons, cloud environments are more > and more popular where "elastic" storage means usually some > virtualized HW storage array. Ah, yes. The "cloud" stuff, where all your data turns into hot vapor. I really do not get why people think using even more complex environments that they do not even fully control is a good idea when we obviously have not even mastered simpler systems... > Also there are SSD drives which uses internally RAID0 to speed > up operations (in reality it is more independent SSD drives inside). Ok, but I think _that_ does not count, unless you know of some that expose the controller. ;-) Arno -- Arno Wagner, Dr. sc. techn., Dipl.
