Addonics 2 Port eSATA II PCI Express Controller with RAID 5/JBOD

This PCI Express controller offers the latest 3G/sec SATA performance and configuration flexibility at an amazingly affordable price. Comes with 2 eSATA II ports for external SATA connection. The controller can also be installed in low profile PCs using the bundled low profile bracket. The two ports can be configured as individual ports, as RAID 1, 0, 0+1, RAID 5 or JBOD. The controller is also Port Multiplier compatible, thus offering potential expansion capability and new storage solutions.

• 2 eSATA ports
• Install into both standard height or low profile system.
• Install in PCI-Express BUS
• Fully compliant with SATA II and SATA 1.0 standard
• Maximum 3Gbits/sec per port
• Supports NCQ commands
• Compatibility with Port Multiplier
• Silicon Image chip set SiI 3132
• Use as a non-RAID or RAID controller
• Upgradeable firmware
• Hot swap support - drive can be removed and added without system shut down or restart *
• eSATA connector for more secure connection, reliability and supports up to 2 meters cable length
• Compatible with drivers for Windows 2000 , XP, and 2003 Server

*Note: It is common in RAID5 configuration that the WRITE speed performs slower than READ. Depending on system hardware, the WRITE performance can drop to 25% of the READ speed. This performance difference does not affect general database application where majority of the transations are READ commands. For applications that require large files transfer or continuous writing of data on the the hard drive such as video editing, RAID5 configuration may not be desirable.

* Hot swapping hard drive has been tested on Windows OS only. When drives are configured as RAID 0 and certain RAID combination, the removal of the hard drive will result in breaking the RAID set and result in data loss.
