The Adaptec Embedded Serial ATA with HostRAID Controller
Driver
The Adaptec Embedded Serial ATA RAID Controller adds SATA/RAID functional-
ity and performance enhancements to a motherboard. RAID striping (RAID 0)
allows data to be written across multiple drives, greatly improving hard disk I/O
performance. RAID mirroring (RAID 1) allows data to be simultaneously written
to two drives, improving data security even if a single hard disk fails. A Stripe of
Mirrors (RAID 10) provides multiple RAID 1 mirrors and a RAID 0 stripe, maximiz-
ing data security and system efciency. By incorporating the Adaptec Embedded
Serial ATA into the motherboard design, Supermicro's C2SBA+II offers the user
the benets of SATARAID without the high costs associated with hardware RAID
applications.
