FastTrak S150 TX2plus
Promise originally designed the FastTrak S150 TX2plus as a cost-effective, high
performance RAID controller card that adds performance and/or reliability to PC
desktops and/or servers using Serial ATA drives.
FastTrak S150 TX2plus has three independent data channels to support a
maximum of two Serial ATA drives and two Ultra ATA/133 drives. FastTrak S150
TX2plus 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 FastTrak S150 TX2plus striped array can double the sustained data transfer
rate of Serial ATA drives.
FastTrak S150 TX2plus 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, FastTrak S150 TX2plus uses
the mirrored drive (which contains identical data) to assume all data handling.
When a new replacement drive is later installed, FastTrak S150 TX2plus
rebuilds data to the new drive from the mirrored drive to restore fault tolerance.
