Thinking of doing 2x 22TB raid 1 on my motherboard (alien.top)

I am thinking of grabbing 2x 22TBs and putting them in Raid 1 using my motherboard SATA ports. The data isn't irreplaceable, so I simply want redundancy against a single failed drive.

However, I have two questions.

- Is the raid controller required to access data on Raid 1 drives? Let's say I take out a single drive, breaking the array, and put it in another system. Would my data still be accessible on that new system outside of the array? It's a simple mirror, so I assume so?

- If I swap my motherboard later, how big of a headache is the process to get raid 1 moved over?

Thanks.

What os?

I'd suggest Linux software raid, with the answers no and easy.

    Motherboard raid is pretty standard. It's been 10 years since I've played with it, but back then you could migrate motherboard raid1/5 across any motherboard and even from intel to amd. I doubt it's changed much.

    I doubt you'll find official documentation on it though.

    I am not saying what is best, but other options would be a software raid like (newer) Windows storage spaces and (older) dynamic disks, on Linux LVM, is similar; if it is only a two-disk array, you can even get a cheap or not cheap raid card, or even less dependent is have 1 be a continuous sync to the other. (This would have the most performance downside, but the pro is it will have the smallest stack of technology when accessing the data on new hardware.
