Spanned Volume - How disk writes are performed
Posted on 2013-12-13
How would having a spanned volume help or hurt me in this scenario? I have 4 physicial disks comprised of 4 distinct volumes:
Disk 1, Volume 1 = system (250GB)
Disk 2, Volume 2 = data (2TB)
Disk 3, Volume 3 = backup (2TB)
Disk 4, Volume 4 = backup (2TB)
If I were to convert Disk 3 and Disk 4 to dynamic disks and span volume 3 across both, how will my backup data be written to that 4TB spanned volume? Does data get written to Disk 3 in the volume until it is full, then continue to Disk 4 in the same volume OR does data get written to either disk at random? My ultimate question or concern is that if I lose one physical disk in the spanned volume, what backup data will I be left with (if any)?
