Raid5  SATA II -3Gbps External 4Ports 64bits PCI-X Host

"Volume  Delivered"

SATA II-3Gbps External 4Ports PCI-X card with eSATA External connectors to  support NCQ, Port Multiplier, Raid5, Raid10, Raid0, Raid1and JBOD!

RAID 0 (Striping), RAID 1 (Mirroring), RAID 0+1 (mirrored-stripping), RAID 5 (Distributed  Parity RAID) and JBOD (Just Bunch of Disks) manage multiple disk drives to  enhance I/O performance and provide redundancy in order to withstand the failure of any individual member, without the loss of data.


  • Four eSATA fully compliant External connectors on the card

  • 48 bits LBA can Break Capacity-Limit to Support HDD larger than 137GB

1. PCI-X

  • Compliant with PCI-X Specification, revision 1.0a

  • Supports 133 MHz PCI-X with 64-bit data
  • All registers appear in unified memory space
  • Full-chip command completion status accessible with single PCI-X burst access
  • I/O port access to register space

2. High Speed Serial ATA

  • Fully compliant with Serial ATA 1.0a and Serial ATA II Extensions to Serial ATA 1.0a Specifications revision 1.1 

  • Hot-plug capability

  • Supports Serial ATA Generation 2 transfer rate of  3.0 Gbps

  • Supports Serial ATA II Port Multiplier1.0 Specifications revision 1.1

  • Supports First-party DMA commands forNative Command Queuing (NCQ)

  • Output Swing Control

  • Supports four independent Serial ATA channels

  • Independent Link, Transport, data FIFO, command  fetch, scatter/gather, and command execution

  • 31 Commands and Scatter/Gather Tables per Port

  • Four Pin header on board for Device LED  connection

  • Protocol Override per Command

  • Staggered Spin-up Control 

  • RAID 5 (Distributed  Parity RAID) has Highest Read data transaction rate and Good  aggregate transfer rate

  • JBOD is a virtual disk that combines all disk drives as one entire disk drive

  • Provides RAID 0 (Stripping) to greatly increase  the performance of data transfer by simultaneously writing data to  multiple drives

  • Provides RAID 1 (Mirroring) to protect the data  from a disk failure by writing identical data on 2 drives

  • RAID 0+1 (Mirrored-Stripping) combine both Striping and Mirroring technologies to provide both the performance  enhancements that come from Striping and the data availability and  integrity that comes from Mirroring

  • Completely with drivers for Windows 2000 ,XP and 2003 Server
