The speed of operation is excellent in comparison to other RAID modes. In this mode, the data is simultaneously written to two disks. Thus, the storage capacity of a two-disk array is combined into a single disk and the capacity is limited to the size of the smallest disk. Span Spanning provides another maximum capacity solution, which some call it as "Large".
Spanning combines multiple hard drives into a single logical unit. Unlike Striping, Spanning writes data to the first physical drive until it reaches full capacity. When the first disk reaches full capacity, data is written to the second physical disk. Spanning provides the maximum possible storage capacity, but does not increase performance. In this mode, the data is simultaneously written to two or more disks.
Thus, the storage capacity of the disk array is limited to the size of the smallest disk. My option now is to either switch the current drive to be dynamic disk and then span the volume onto the new drive or I can set it up as a striped volume.
I have space available to back up my files since I assume striping will need a reformat of the partition. What would be my best option? I'm tempted to go striping because of the probably small transfer speed increase. But spanning would I presume have less CPU overhead.
And would spanning allow me to recover files if one drive dies? I know the striping won't allow me to. I don't believe you can stripe the boot drive, even on XP correct me if I'm wrong.. Example: If you have two disks which are using mirroring technique for writing data, the data will be written like below:.
Spanning : Spanning provides another maximum capacity solution. Unlike stripping, spanning writes data to the first physical drive until it reaches its full usable storage capacity.
When the first disk is reached to the full usable capacity, data writing starts in second physical disk. Example : If you have two disks which are using spanning technique for writing data, the data will be written like below:.
