Advanced Hardware Design
Features Benefits
Supports 66 MHz PCI bus motherboards
(automatically backward compatible with
33 MHz PCI slots)
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.
Supports:
data striping (RAID 0) and mirroring (RAID 1)
Provides dramatic increase in drive performance and/or fault
tolerant options. Offers performance customization and data
rebuilds from the BIOS menu.
Supports SATA Specification Burst data transfer rates up to 150 MB/sec from SATA drives to
boost overall system performance.
Independent data channels for SATA drives Drives can multiply their data transfer performance when striped
together and each drive uses a separate data channel.
PCI Plug-n-Play, PCI Interrupt sharing and
coexists with motherboard IDE and SCSI
controllers
Easy to install; supports two SATA drives while still supporting
four devices on the motherboard ATA controller.
Supports IDE bus master operation 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.
