Benefits
Allows maximum data transfers of up to 266 MB per second (133
MB/s in 33 MHz slot) over the bus to dramatically reduce the time
to save and retrieve large files.
Provides dramatic increase in drive performance and/or fault
tolerant options. Offers performance customization and data
rebuilds from the BIOS menu.
Burst data transfer rates up to 150 MB/sec from SATA drives to
boost overall system performance.
Drives can multiply their data transfer performance when striped
together and each drive uses a separate data channel.
Easy to install; supports two SATA drives while still supporting
four devices on the motherboard ATA controller.
Allows multitasking during disk transfers that increase CPU
efficiency. The CPU is free to process tasks during IDE data
transfers through the PCI Bus to/from system memory.
Has "Auto Setup" option for quick and easy array builds.
Notifies user of possible errors and allows for recovery of mirrored
drive arrays directly from EasyBuild.
Fully supports SATA specifications with 150 MB/sec timing and
CRC error-checking at high speeds.
Fault tolerance can be restored automatically without rebooting.
