Home > Products > Host Controller > 4 Port eSATA RAID5/JBOD PCI-E 8x Controller

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 RAID firmware, the 4 eSATA ports can be easily configured as 4 individual ports with no RAID or with RAID 5, RAID 0, RAID 1, RAID 10, RAID 1+S, or JBOD (a feature of combining all 4 drives into one large capacity hard drive)

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)

Throughput exceeding 240 Bytes/sec sustained data transfer can be achieved using standard 7,200 RPM SATAII hard drives by setting up 4 drives in a RAID 0 configuration (see benchmark test result below). Together with the Addonics Storage Tower, Disk Array system and various Addonics Mobile Rack, you can add external high performance storage system that rivals the traditional SCSI storage at less than half of the cost.

Mac Pro version of this controller also available. Click here for the product page.

Product Features

• SATAI and SATA II compliant
• PCI-Express 8 lane compatible (also fits into PCI-Express 16 Lane or the graphic card slot)
• Up to 300 Bytes/sec (3 Gbits/sec) per port
• 4 External SATA (eSATA) ports
• Works with any Serial ATA drive

  Built-in RAID 0, RAID 1, RAID 1+0, RAID5 and JBOD support (illustration on the left is the bundled RAID utility for Windows OS)

• Support large hard drives of 137 GB or greater
• 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

*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.

Part number and Pricing

Since the eSATA connector on this adapter is new to the market, connecting cable with this new connector may not be readily available. Addonics offers a complete cabling solution for External SATA applications. All Addonics external SATA cables are constructed with metal clips on the connectors for reliable repetitive insertion and tighter connection needed for external application. These cables are also heavily shield and wired to increase EMI protection and ensure SATA signal integrity in external application over a 2 meter distance.

Option 1: External SATA (eSATA) - SATA converter cable (model AASA2SAP15C, 15 cm.) plus External SATA data cable (model AASAEDC3F, 100 cm.)

The 15 cm. cable (AASA2SAP15C) converts the new eSATA connector back to standard SATA External connector plug. Together with the standard 100 cm. External SATA cable (AASAEDC3F), SATA storage device can then be connected to this controller. This combination gives the flexibility of connecting any external SATA device , to this eSATA controller or *PVR/Set Top Box to the standard SATA ports that are commonly found in most of today's SATA equipped systems.

Option 2: eSATA - SATA cable (AASA2SA100C, 100 cm.)

One end of this cable has the new eSATA connector for connecting to this eSATA controller, *PVR or Set Top Box. The opposite end has the the current standard SATA connector for connecting to SATA hard drive or other Addonics external SATA storage devices.

*At the present time, some PVRs (a few models from TiVo) and Set Top Boxes are equipped with this new eSATA connector.
