Storage
The C612 chipset supports two SATA AHCI controllers, sSATA and SATA. The sSATA controller supports four 6 Gb/s ports
and RAID modes 0, 1, 10 and 5. The SATA controller supports two 6 Gb/s ports and RAID modes 0 and 1. Ports from both
controllers can be routed to the rear panel with an eSATA bulkhead option. Note that it is not possible to RAID across the
two SATA controllers.
The optional HP Z Turbo Drive featuring a PCIe connected SSD is supported on this platform and provides performance
levels greater than 1 GB/s. Up to two Z Turbo drives can be configured in the factory. Data RAID is supported through
Microsoft Windows Disk Manager.
