SP3) and Windows Vista® SP1 operating systems.
Devices supported
This section describes the devices supported for RAID migration, including the SATA drives, computers,
and docking station. Device support is summarized in the following table and then explained in more
detail below the table. External USB 2.0 SATA drives connected to the computer or docking station
cannot be used for migrating to RAID.

HP SATA drive option kits
HP offers SATA drive option kits for the notebook PC Upgrade Bay and the docking station SATA
swappable bay to support RAID migration. For optimal RAID performance, it is recommended that both
drives have the same speed. However, supported HP Business Notebook PCs allow drives with different
speeds to be used in a RAID volume.
Drives of different capacities are also supported for RAID migration, as long as the capacity of the
secondary (recovery) drive is equal to or greater than that of the primary drive. For example, if the primary
drive is 200 GB, then at least a 200-GB drive is required in the Upgrade Bay to create a RAID volume.
If the capacity of the secondary drive is larger than that of the primary drive, the excess capacity of the
secondary drive will not be accessible. If, for example, the primary drive is 160 GB and the secondary
drive is 250 GB, only 160 GB of the secondary drive will be usable in a RAID configuration. Therefore,
for optimal use, it is recommended that both drives have the same capacity.
