#1, #2, #4, #5 are YES
#3 Yes, you can add a drive but I haven't try adding a drive to an existing array. It simply shows up as one more drive in JBOD.
#6 The controller do add power. If you need ports beyond those on the MB, then it is a given. My server is very low power in any case.
Once you added ports via controller cards, HW RAID is free from the controller card vendor. SW RAID will cost money by a 3rd party.
If you don't look of course you fail to see. If you didn't see how can you say it doesn't exist?
You have to replace the controller with the exact same controller if the controller fails to get your array back, correct?
If I were to pull a drive out of your array the data would not be accessible on another machine, correct?
You can't add full or partially full drives to an existing array, correct? You stated that you can but I don't believe this to be correct.
You can't add full or partially full drives to a new array, correct?
You can't use green drives, correct? This is what I meant by non-server hardware.
You have to use "server hardware" i.e. a controller card, correct?
It costs usually more than software raid because you have to buy a $50-$200+ controller card and cables, correct?
In most raid arrays you have to use drives of the same size or risk losing some of the possible storage, correct?
Again, correct me where I am wrong or mistaken. And BTW a raid controller on a motherboard is not the same thing as a hardware/controller card solution.
