When is serial ATA coming
And will it be price competitive to IDE 
. Will I need a new mainboard or additional controller? How many drives are supported?

All sounds like nice marketing stories; 'OS transparent' and no indication how the hardware would be compatible. At the same time 'all hardware issues should be resolved'.

| The goal of the working group is to ensure the Serial ATA transition happens as smoothly and quickly as possible. The Serial ATA specification is expected to be complete in the fall of 2000 with adoption to happen in the following 12 to 18 months. |

| Serial ATA electronics and connectors will differ from Parallel ATA, however the technology is software compatible and OS transparent. It is anticipated that there will be adapters to facilitate forward- and backward-compatibility of hard disks on PC systems |

You will need a new PCI card to make this work in your existing system.
You will eventually be able to get motherboards with both old and new controllers on them, but not anytime soon.

What advantage would it have over SCSI? Ultra 160 drives with large caches are cheap and fast and SCSI is well supported. And Windows always has good drivers for Adaptec and other leading SCSI controller providers.
Hi All:
___The advantage will come in the form of > 133 MB/s that we are currently restrained to on a std. consumer based chipset’s PCI bus no matter if we RAID or use SCSI cards on the rather slow PCI bus. PCI-X gives us up to 8 times this but I have only seen the dually boards using anything even close to 2X the std. PCI bandwidth (Tyan Tiger MP) or the AMD 760MPX w/ 4X the PCI std. – 533 MB/s for some 66 MHz cards in their respective 66 MHz/64 bit slots and the 133 MHz std. for std. PCI based cards. I remember reading about the serial ATA std. coming in at 200 MB/s initially and doubling in bandwidth at relatively short intervals thereafter. Not that any of today’s drives in Primary/Secondary Master/Slave relationships can even come to saturating the PCI bus, it won’t be long when multimedia/video of some kind probably will.
___Good Luck
