Adaptec Embedded SATA with HostRAID Controller Driver
The Adaptec Embedded Serial ATA RAID Controller adds SATA/RAID functionality
and performance enhancements to a motherboard. RAID striping (RAID 0) allows
data to be written across multiple drives, greatly improving hard disk I/O perfor-
mance. 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, maximizing data
security and system effi ciency. By incorporating the Adaptec Embedded Serial
ATA into the motherboard design, Supermicro's X7DBR-3/X7DBR-E offers the user
the benefi ts of SATARAID without the high costs associated with hardware RAID
applications.
