I suspect that the write overhead may | be fairly high, leading to a lot of dead time while writing (the read | overhead is also an issue I guess). I haven't done a lot of timing tests, | as I'm typically more concerned with functionality and reliability. Are there any other IDE RAID cards supported under FreeBSD? I had been considering this one when I read about a few weeks ago, but if RAID1 is a dog, it's kind of worthless to me. Is RAID0 still faster than a single IDE disk? My first use for one of these cards would be a RAID0 SQUID cache, the other uses would have been RAID1. They're cheap enough that it might be worth getting a couple for the hell of it.
