The new Addonics eSATA II RAID5/JBOD controller ensures maximum data throughput of 3 Gbits/sec per port when installed into the PCI-X bus. The controller features the latest eSATA connector to provide EMI protection, improved durability, and a complete cabling solution to ensure SATA signal integrity in external applications up to seven feet.
Throughput of up to 200 Mbytes/sec sustained data transfer can be achieved using standard 7,000 RPM SATA hard drives by setting up four drives in a RAID 0 configuration. The controller can also be combined with several optional Addonics Drive Enclosure solutions including the Disk Array 4SA system, Saturn Hard Drive kit or the external SATA drive enclosure. These solutions would allow users to build an external storage system that achieves similar performance of traditional SCSI storage, perfect for NAS, SAN, RAID and non-RAID storage arrays at less than half the cost.

port-multiplier and PCI compatible3/26/2011
I've got a Dell Inspiron 530, an external port-multiplier (AD5ESAPM-E), two multi-drive enclosures with built-in multipliers, an eSATA DVD-RW, and no free PCI-E slots. I could not find a port-multiplier-compatible PCI eSATA controller, with 4 ports, at any price -- but there were a few PCI-X cards that fit my needs, and this was the cheapest that guaranteed "PCI compatible" in the specs. (Just make sure nothing on your motherboard will block the extra fin.) Sure enough, the card works perfectly in the PCI slot, and installed in Windows 7 Pro (32-bit) without a hitch. Performance is good, and hot-plug works smoothly. I had no use for the RAID features, but be aware that this is a "SoftRAID" card, not a true hardware-based RAID controller -- so don't expect good RAID performance.
RAID5 not supported on Mac3/10/2008
I purchased this card specifically for its RAID5 capabilities. I was not looking for high speed, just a hardware RAID5 card to use with my 5 bay eSATA port multiplied box. Unfortunately after getting in the card and installing I found out that RAID5 support is only available for Windows. I did some read/write tests and found this card to be about 30% slower than my Sonnet X4P card as well. All in all I'm dissatisfied with the fact that the sole reason for purchase is not supported on my platform. That said, the card does seem to work fine as just an eSATA HBA (albeit not as good a performer as the Sonnet card).
Works great, fast through put.1/24/2008
Installed in an older Dell Poweredge 2600 server. Running Windows server 2003. Card and drivers installed with no problems. Required a re-boot. Getting very fast through put to an external Calvary USB/ESATA drive. Tried USB 1.0 performance before this card, but USB was terribly slow.
