m-of-n USB cold storage native in Windows Server 2008+?

[Kluge]

Convert USBs to dynamic disks with the disk manager. Convert to RAID 5 or 6 in WinServ 2008 or 2012 (anyone know a way to force Windows 7, 8, or 10 to software-manage fancier RAID configs?).

Poof - you now effectively need m of n USB disks to access your coins with minimal effort on your part (do you need to match the USB ports? Beats me!). You're welcome (I have no idea what happens if you start writing some updated wallets or keys to some USB sticks and not others, and then try to write to those others later without rebuilding). The Internet suggests you can also natively do this in some linux distros.

cons: can't do this with paper wallets, requires 3+ removable devices, not extendable to m-of-n (can only support  n-2 <= m <= n). I don't see what's the point of this idea when there's m-of-n transactions implemented natively.

Is it native, now? I'm still on... uhh.... 9.2.1 -- maybe time to upgrade.
