The FastTrak S150 SX4-M Overview
The FastTrak S150 SX4-M Serial ATA RAID PCI adapter delivers industry-leading RAID 5
performance at an unprecedented performance-to-price ratio. For companies running
popular applications like web services, file/email servers, audio/video streaming and nearline
storage, the FastTrak S150 SX4-M opens the world of professional RAID 5 performance
and data protection and combines it with cost-effective Serial ATA (SATA) drives for the
ultimate internal storage solution. Based on OEM-proven RAID 5 technology, the FastTrak
S150 SX4-M competes with SCSI RAID 5 controllers— at one-half to one-third of the
price. RAID 5 storage protection is no longer the privilege of budget-rich IT departments.
Maximize RAID Performance with Serial ATA Drives
The FastTrak S150 SX4-M is designed for RAID-perfect Serial ATA. Serial ATA is an
evolutionary replacement for the Parallel ATA physical storage interface.The Serial ATA
standard incorporates highly anticipated features that are ideally suited for ATA RAID use
such as:
:: Thinner Serial ATA cables up to one meter long to provide flexible routing and better airflow
:: Simpler drive configuration, jumper setting is no longer required during installation
:: Point-to-point configuration to support one drive per cable and achieve performance scalability
:: Higher availability with hot pluggable drive support
:: Enhanced reliability with CRC error checking on all protocol phases
Promise Hardware-Assisted RAID 5 Architecture
RAID 5 implementation involves striping data and parity information (XOR) across the
storage array. Since those parity calculations are so processor-intensive, RAID 5 controllers
traditionally require a dedicated CPU to perform the XOR calculations and manage the
array. Instead of adding a costly CPU to the controller, Promise’s FastTrak S150 SX4-M
controller uses an integrated XOR engine for parity calculations, delivering extraordinary
performance at a dramatically lower price.This approach takes advantage of today’s ultra-
powerful PC CPUs to manage the array and outperform traditional RAID 5 solutions.The
FastTrak S150 SX4-M sets a new standard for RAID 5 controllers.
