RAID mirrored systems

[loanrangie]

Haven't played around with this before but i picked up an i7 PC that has 2 x 1tb WD drives setup up in a mirrored RAID configuration, when the PC boots up it shows 2 HDD's in the bios but then in windows explored it only shows 1 hdd and only 1tb .
I assume this is how it should be as its a redundancy system if 1 drive fails ?
While i was checking it out i unplugged each hdd separately and it booted from either drive into windows, i removed one of the drives and then loaded win10 onto as i'll probably wipe it in another PC then put it back for storage.
Out of interest, if i put it back will it copy the updated drive onto the 2nd drive ?

Edit, so its a RAID 1 array and putting the drive back it should be mirrored again.

Raid 1 will write over the added disk to rebuild the array, you will need to break the array if you want to use the disks separately.
Is it software raid setup in Windows or does it have controller?

It's software RAID but with enough smarts in the BIOS to be able to boot it up. All the trickery is in the Intel Windows driver. Been standard on most Intel boards for years.
