Stay away from HighPoint.... The don't have real SATA controllers. They 
use the old PATA with PATA/SATA bridge. Besides that, I had problems 
with the latest kernels (kernel panics after a while). I have a 1540 
here (same beast as 1640 but without "RAID") to get rid of :(

Oh, and remember that none of those boards are real RAID. All are 
softraid.  You're better of using a standard SATA borad and linux 
softraid or using a real SATA RAID card like 3ware and I think Adaptech 
and Promise also have some hardware SATA RAID controllers.

If you go the cheaper softraid way, I'm using these on a server:
0000:04:01.0 RAID bus controller: Silicon Image, Inc. SiI 3114 
[SATALink/SATARaid] Serial ATA Controller (rev 02)
0000:05:04.0 RAID bus controller: Silicon Image, Inc. SiI 3112 
[SATALink/SATARaid] Serial ATA Controller (rev 02)
**
First one is 4 ports and the other is 2 ports.

I'm using it with 4x200GB (soft RAID5) and 2x80GB (soft RAID1) without a 
problem. Performance is good but if you can afford a real hard RAID card 
it should perform much better (3ware and Promise cards even have onboard 
cache using standard memory modules).

Just my $0.02 ;)

Cheers,
Fed.
