RAID configuration. Therefore, for optimal use, it is recommended that both drives have the same capacity.
eSATA HDDs (select models only)
External SATA, or eSATA, is an external interface that allows a SATA drive to achieve data transfer speeds up to 6 times that of a SATA drive using a standard USB 2.0 interface. The following illustration shows a supported computer with a primary HDD (1) and an eSATA drive (2) connected to the eSATA port (select models only) to allow Recovery. Regarding the capacity of the eSATA drive, the same recommendations apply as stated for secondary drives in the computer Upgrade Bay.
HP Business computers
Select HP Business computers support RAID using Intel® Rapid Storage Technology software (v10 and higher) and a second SATA drive in the Upgrade Bay.
The following illustration shows a supported computer with the primary HDD (1) and a secondary HDD drive in the Upgrade Bay (2) that allows RAID 0, RAID 1, and Recovery.
