PDC20319 SATA RAID Controller
Promise originally designed the PDC20319 SATA RAID Controller as a cost-
effective, high performance RAID Controller that adds performance and/or
reliability to PC desktops and/or servers using Serial ATA drives.
The PDC20319 SATA RAID Controller has four independent data channels to
support a maximum of four Serial ATA drives and it supports:
•
Striping (RAID 0) – Identical drives can read and write data in parallel to
increase performance.
•
Mirroring (RAID 1) – Mirroring increases read performance through load
balancing and elevator sorting while creating a complete backup of your
files.
•
Striping / Mirroring (RAID 0+1) – Combining striping with mirroring offers
both high read/write performance and fault tolerance
A Striped array can double the sustained data transfer rate of Serial ATA drives.
The PDC20319 SATA RAID Controller offers fault tolerant, data redundancy for
entry-level network file servers or simply for desktop PC users wanting to
continually protect valuable data on their PC. Each model offers RAID 1
mirroring (for two drives) and RAID 0+1 mirroring plus striping (for four drives) to
protect data.
Should a drive that is part of a mirrored array fail, the PDC20319 SATA RAID
Controller uses the mirrored drive (which contains identical data) to assume all
data handling. When a new replacement drive is later installed, Controller
rebuilds data to the new drive from the mirrored drive to restore fault tolerance.
The PDC20319 SATA RAID Controller’s bootable BIOS supports individual
drives larger than 137 GB. With FAT32 and NTFS partitioning, the array can be
addressed as one large single volume.
