Here's some info on mirroring controllers. I thought the $700 sounded
high.
In the most recent issue of Computer Shopper, there are at least two
companies that sell the controllers.
Dirt Cheap Drives (800-473-0960) has one for $139 and Dalco
(800-445-5342) has one for $111. (Dalco part number 55145) The people
at Dalco were especially courteous and helpful. They are available for
ISA, PCI, SCSI.
I want to reiterate that I have never used these since I prefer to
backup to removeable media. I have no idea how well they perform,
whether they impose a performance penalty on your computer, require
interrupts or other resources, are compatible with WIN95 or other
software/hardware,etc. I'm sure I don't have to tell you, but I would
buy something like this only with an unconditional money-back guarantee.
They do seem to offer convenient protection against hard disk failure,
but that's about it as far as I see.
I hope this helps.
Mike
