[olug] Promise FastTrak 100

[Brandon Lederer]

I guess I am concerned about the processor overhead in a server.  Or is
there not that much overhead for mirroring.  I understand how striping would
have serious overhead.

So which is better?  Linux Software RAID in the kernel or the Promise
ATARAID TX controllers?  3ware is the only Hardware RAID for IDE?

Yes, with the Promise ATARAID controllers, it is 95% software raid. The
drivers do the work, not the hardware. If you wanted to be cheap, there is
only a small modification needed to the regular promise ata PCI
controllers to make them function like the TX raid controllers.
