What the bus does is very high pumped speed HD access via a serial connect-- the throughput is comparable to firewire plus 10% or so, and the data flow is serial with separate dedicated control lines on the same connector. Typically it is run inside the FSB area of a mainboard, and to a degree will imitate ATA. It is intended for HDs with 10,000 to 15,000 or higher rotational speeds and thus very low average seek times. Silicon Image, Promise, and HighPoint Technology are touting these. The earliest drives for this are in the price range of Maxtor's fiber channel drives, as the same basic mechs are needed for both S\ATA and fiber channel to support the high speed access.

01:0b.0 RAID bus controller: Silicon Image: Sil3112 Serial ATA (rev 01)what is this module?
...
as the kernel also know about:
SiI3112 Serial ATA: IDE controller at PCI slot 01:0b.0
SiI3112 Serial ATA: chipset revision 1
SiI3112 Serial ATA: not 100% native mode: will probe irqs later
thanks!
/usr/src/linux/drivers/ide/pci/siimage.c
but if that would be built as a module, it should have the name siimage, shouldn't it...

What is being discussed now is the degree to which one will be able to hot-swap these drives like SCSI drives can so be swapped. It is proposed, and most agree, that it will be as hot-swappable as SCSI or USB or Firewire. The connector Pics I have seen are smaller, 10-16 wire connectors. They are not pure fiber connect.
Some of the new VIA and Intel mainboards that support 3+ GIG CPUs allow for these drives, but they right now are future tech given the mech. prices for about 90% of the public. We do not need to heavily worry about these particular busses right now, IMHO, but in 2 years when R&D costs of mfrs. are somewhat paid for, they may start to become very popular in things like backup appliances and high-end cluster storage units, especially for those heavily into animated high quality graphics.
