SCA SCSI RAID

Given the bandwidth that 4 drives would need I am assuming you would like a PCIe controller over a standard PCI card. Thats going to be difficult on that budget.

SAS is meant to be an upgrade for the older SCSI server system and has much more support under PCI-X.

The PCIe versions are relatively new and somewhat expensive.

PCIX is the old 64 bit PCI bus

You can recognize it like a longer PCI (or a normal PCI with another slot just behind in line, like the old VESA thas was a ISA plus another conector in line)




It is used mainly in servers/workstations before PCI Express and will be hard to find on a normal desktop mobo.


PCIX cards are compatible with normal PCI slots but dont waste your money on that setup, the normal PCI bus is no fast enough and will bottleneck your
system.


I found this the hard way after purchasing an LSI Megaraid card

I'd suggest go to ebay and look for scsi raid cards with PCI Express connectors, maybe you can find a "cheap" one...
