Well I have up at 1.1TB/11Disk now and I am _NOT_ stopping.
And the reliability should not be a problem because it is not a disaster if disk goes down.
The thing is that all money comes from my pocket and my pocket only so I need to keep it cheep ;)
Thanks for the advice I will mail Promise to hear what they got to offer.

theSo what you REALLY want is a lot(!) of ATA disks that can be connected somehow to a Linux box? :-)
If you're sure you want to use ATA cards, I'd suggest getting hold of Promise or HighPoint and first send an email to their respective support addresses and ask if there are any issues with using that many cards. I'd wonder about IRQs and if all the BIOS will conflict or not?
My big concern would be reliabilty - It would be worth looking at products specifically designed to handle lots of disks. How many do you plan for? 6 cards * 2 channels/card * 2 drives/channel = 24 disks... (with 100GB+ disks is a lot of storage) For that scale, SCSI to ATA-RAID systems like Promise UltraTrak are not a bad idea... and if it's just a dumb fileserver, some form of NAS might be a lot easier.
Anyway, have a look on www.promise.com, as well as www.3ware.com and www.highpoint-tech.com for their "big" cards / systems.

If you want more info, can you post your intended purpose / setup to
onlylist? Eg, why 6 controllers?Will do :D
I it is going to be a file server and im not in need of the ATA RAID
linux, imthe ATA controller
So what I want is a lot of ATA controllers that works together in
not in need of any speed (more then ata66 anyway).
Be aware there are a number of people on lkml that have reported they can't get 3+ promise cards working. I've personally tried and wasn't able to get more than 2 working. It really comes down to how much your time is worth. The configuration you're proposing will not work on the 1st or 2nd try. Even when you get it working I doubt it will work well.
