@comcast.net | SCSI or SATAII
I came across two working pci-x disk controllers, a mega raid SCSC and a mega raid SATAII. I have no hard drives for either. Witch would be faster and worth the money to buy drives for. |

| Well unless you have a lot of cash to burn, SATA is going to be the more 'economical' as far as cost/Gig. You can get faster SCSI drives (15k RPM) but you're going to pay a lot for them.
Most people probably wouldn't be able to tell the difference between the two as far as data transfers go.. |

Stick with SATA. That is the norm for the vast majority of situations, especially for the typical desktop computer.
Your situation doesn't sound like it would benefit from scsi and, as jahntassa said, cost is higher. |

I'm sorry I read your post too quickly and missed that you are discussing a pci-x card. Are you wanting to put this into a home desktop?
Could you describe a bit about what kind of system you are wanting to use this for and the purpose of the machine? |

3ware hasn't made SCSI cards in a while, so I'd guess the SATA card is newer (model numbers would help refine an answer) and probably the better bet. Besides, SATA drives cost much less. |

Depending on what you want with them. You can get 15k, 18G SCSI drivers of eBay for dirt cheap, but for most uses, you'd be better off with some 250G - 750G SATA drives. |

SCSI HD has less and less advantage over IDE/SATA drives. Aside from being more expensive, SCSI has hardware base controller to do a dedicated job and you can hook up to 15 SCSI devices these days.

| said by ChiTang  : SCSI has hardware base controller to do a dedicated job For one thing, modern drives do not need a separate controller unlike the ST406/512 vintage since the controller is now part of the drive electronics. And as far as I know, in all cases, they are part software (firmware) and hardware, regardless of the interface.
Likewise, the host adapters are also part software and part hardware. Firmware is mandatory for SCSI (even for the simplest and cheapest one) but it may not necessarily be needed for a simple IDE HA, though nowadays all HA has some firmware. |

I am not exactly sure the current trend of SCSI controllers these days (some are as cheap as $30.00). I stoped using them a few years back. I am kinda understanding why some newer controllers become part software and part hardware. I'll take your info at its face value for now, thanks for the info.

untrue .. 3ware makes lots of SAS cards.
SATA and SAS share the same backplane.
SAS is alot faster then SATA. SATA is your best option though unless you want to spend big $ |
