Не знам дали върви успешно...не ми е това областта.Правено е. Доста по-бавно от RAID-0, положително по-сигурно от него.

Creates a RAID-5 volume on the specified dynamic disks. After you create the volume, the focus automatically shifts to the new volume.
Syntax
create volume raid [size=n] [disk=n[,[n,…]] [noerr]
Parameters
size=n
The amount of disk space, in megabytes (MB), that the volume will occupy on each disk. If no size is given, the largest possible RAID-5 volume will be created. The disk with the smallest available contiguous free space determines the size for the RAID-5 volume and the same amount of space is allocated from each disk. The actual amount of usable disk space in the RAID-5 volume is less than the combined amount of disk space because some of the disk space is required for parity.
disk=n
The dynamic disks on which to create the volume. An amount of space equal to size=n is allocated on each disk.
noerr
For scripting only. When an error is encountered, specifies that DiskPart continue to process commands as if the error did not occur. Without the noerr parameter, an error causes DiskPart to exit with an error code.
