Large, depending on the ussage pattern.
That is not quantifying it ;-).
Well, Greg mentioned a price tag of $1500 for such a thing... I'm sure you can find benchmarks around. Just consider that software raid typically is slower than the same disks in singles, visibly so; thus there is margin to gain.
What advantage is that? You mean that theoretically it would be possible to get a form of software raid that works in both linux and windows?
Of course. I'm saying that "fake raid" does. Not theory.
Yeah, except that my very common chipset is not even supported in Linux ;-).
Well, that's one of the disadvantages. Another is that if the controller or motherboard dies, it is very possible that you will not be able to recover the array on another controller. Instead, you need to restore from backup on a newly created array. This also happens with real hardware raid, of course. Linux software raid is very flexible. If you do want to access that fake raid as such (I understand you don't) you would have to create a new thread with an appropriate tittle so that people that know about that particular chipset can advise you. It is called "dmraid", by the way. If you google "fake raid on linux" you find many hits. For instance, a good one for ubuntu: https://help.ubuntu.com/community/FakeRaidHowto Searching for "fake raid" or "dmraid" on the opensuse wiki search facility finds nothing, although it does exist, according to google: https://en.opensuse.org/SDB:DMRAID «This article describes how to reuse disks after removing them from a DMRAID software RAID array.» Not much use then, I'm afraid. :-( Apparently, "dmraid -l" lists what it supports. - -- Cheers Carlos E.
