linux pci raid card recommendations?

[lf]

Hello,

I recently had an unpleasant experience with a hdd failure in a software
raid5 array.

After at least 10 hours of trying everything I could think of, I finally
managed to get my data off the array, thanks to info from posts on this
mailing list.  (thanks guys!)

However, I didn't really enjoy having to recreate the array, making
absolutely sure to use all the exact same parameters so as not to lose
data.

I am looking for something to make this process more pleasant next time.
I was wondering if the people on this list could recommend a pci SATA
raid5 card that handles hdd failures elegantly.  I'm not concerned with
speed that much.  I want the maximum amount of reliability (read: nicest
linux drivers), and extremely easy recovery from failure.

I've been looking at the highpoint and adaptec 8port SATA cards.  The
adaptec card costs twice as much.  Is it worth it?  Is there some other
card I haven't found that works better under linux than either one?

Any help would be much appreciated.

Thanks,

	Eric

P.S. Please cc me your replies, as I am not subscribed to this list.
Thanks again.

The highpoint card is fakeraid, so I'd consider it overpriced if it
costs half as much as an Adaptec card.

3ware cards have a good reputation, and from what I've seen they work
pretty well.

When using a hardware raid controller, always remember that you are
completely at the mercy of the vendor, since the on-disk format is
generally proprietary.
