1) I don't think "the cloud" as a means of storage will ever replace fast access to data. It might be a good backup, but if you are editing video/etc, you'll want tens of megabytes/sec. Most people don't have internet connections that can touch that.
2) All raid is software. Even "hardware raid" is just software on dedicated microcontrollers. I would therefore change the term "hardware raid" to "proprietary raid". I think you said it best on your more recent video, call it what it is. :-)
My goal of using RAID is redundency over space and speed. So RAID 1 is appealing and theoretically the most easy to recover from with least headaches. When a drive crashes (and they do) you want to have less stress not more.
@windcrest77 When your raid 1 fails, which drive has the good copy? You might say the software should detect this, but what if the computer was powered down incorrectly or you had a voltage spike and not sure which is the good copy? That is why an algorithmic raid such as RAID 5 is superior. If you like entire mirror copies, consider a three drive RAID 1 (mirror). This is only possible with linux software raid as far as I know. (Commercial vendors would restrict you from doing this.)
Thanks for this clear explanation, I have been struggling with this decision for a small home theater machine where I want to have a RAID 1 volume. I am going to consider using the quick easy Windows 7 Pro RAID 1 because I know a drive can be removed and read on another machine as a single drive to be easily re-imaged or simply reused in emergency. If proprietary hardware is writing my files this may not be the case. I'm using SATA III so it should still be plenty fast.
