4 Port eSATA II PCI-E 8x Controller for Mac

Designed to the latest 3Gbits/sec ASIC from Silicon Image and eSATA connector, this 4-port controller incorporates many advanced features that are only found in some expensive RAID controllers. With the onboard BASE firmware, any drives connected will be detected by the system as individual pass-through drives.

When installed into the fast PCI-Express BUS, this controller ensures maximum data throughput of 3 Gbits/sec per port. In addition, the latest External SATA (eSATA) connector also provides more secured cable connection, improved durability, increased EMI protection and up to 2 meters cable length. (For more detail on this new SATA external connector, please review the following white paper posted on SATA-IO.org)

  • Up to 300 Mbytes/sec (3 Gbits/sec) per port
  • 4 External SATA (eSATA) ports
  • BASE BIOS firmware - drives are automatically detected as pass-through devices by the system
  • Software RAID using Windows Disk Management or MAC OS X Disk Utility
  • Support hard drive storage capacity of 2TB or larger
  • Silicon Image chip set SiI 3124
  • Port Multiplier compatible
  • Fits standard height Desktop case
  • Hot swap support - drive can be removed and added without system shut down or restart*
  • Simple plug and play
  • Compatible with Windows 2000, Windows XP, Windows 2003 Server, Vista, Mac OS X 10.4.8+ **

*Note: It is common in RAID5 configuration that the WRITE speed performs slower than READ. Depending on system hardware, the WRITE performance can 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.

**Note: There are currently reports of incompatibility with this controller under Mac OS X 10.6 Snow Leopard. Please check back for updates on this incompatibility.
