4-Port eSATA II PCI-X 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. The 4 eSATA ports can be easily configured as 4 individual ports with no RAID or with RAID 0 or RAID 1 using the Mac OS Disk Utility.

When installed into the fast PCI-X 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)

Throughput up to 200 Mbytes/sec sustained data transfer can be achieved using standard 7,000 RPM SATA hard drive by setting up 4 drives in a RAID 0 configuration (see benchmark test result below). Together with the Addonics optional Disk Array 4SA system, Saturn Hard Drive kit or the external SATA drive enclosure, you can add external high performance storage system that rivals the traditional SCSI storage at less than half of the cost.

*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.

**The final version of PowerMac G5 uses PCI-E BUS slots instead of PCI-X which is needed to install the ADS3GX4R5-EM. Please verify that your G5 has PCI-X slots before purchasing this controller.
