I have never seen any documentation or statement re: SATA HDD units being daisy-chain capable. That said, I have been using both SATA and eSATA II HDD units, mostly for Disk-to-Disk and Disk-to-Tape backups. For the SATA HDD units, which have been internal, most of them are connected via on-board connections on a motherboard. In the one case where I added a SATA card via a PCI slot I selected a Silicon Imaga 3112a SATA Controller. It has performed well, never a problem. Although it is a 1.5gps throughput design a performance choke point will always be found in the standard 32 bit PCI slot interface.
For my 2 eSATA II Seagate FreeAgent HDD units (5 year warranty) I selected a StarTech 2 Port eSATA II PCI-E card, which uses a very high speed PCI Express slot in my Dell 840 Server machine (lifetime warranty). SATA II can kick out up to 3gps throughput in theory, but choke points will be found in other places. It does not use a standard SATA cable, it uses an External SATA II cable. There is a difference, so don't try to sledgehammer one in place of the other <g>. Performance has been excellent, more than fast enough to keep up with my LTO3 External Tape Drive, whereas a slower interface would prevent the LTO3 unit from running as fast as it does now with net i/o. For the eSATA II cables I went to SATACables.com, where they have a great selection and rock bottom prices. I have purchased from them a few times, and have been very satisfied. I hope that helps.
