Hardware RAID on Arch?
Hello~ I'm buying myself a new PC soon and I was really looking forward to putting Arch on it but the problem is is that I cheaped out on the mobo so I have to get a $20 PCI raid card in order to put my new 160gbs in RAID0, the only problem is that of course the only drivers supplied are for Windows, and I'm not sure how to go about doing this on Arch / any other linux distro because I'm simply not the best at the linux environment. So yeah, any comments are appeciated. Oh, and if it matters, here's the link to the card I'll be getting: http://www.newegg.com/Product/Product.a … 6816132008

Re: Hardware RAID on Arch?
That device has a Silicon Image SiI 3132 chipset, which is apparently supported by the sata_sil24 module in the kernel.
No gurantees - that's just what I found in 2 quick Google searches

Re: Hardware RAID on Arch?
Okay, well if it's supported, how would I set it up just like in the software raid article I read?

I think you're getting confused now...
Software RAID and Hardware RAID are separate things. If you have Hardware RAID, you don't need to use Software RAID. The RAID array will just appear like a normal hard drive to Linux and the Hardware controller will take care of the RAID part.
Software RAID can be used instead of hardware RAID to save costs (no hardware controller required). Software RAID is generally slower than hardware RAID, but not noticable in desktop applications.

Re: Hardware RAID on Arch?
The SI3132 card you reference is not a true hardware raid card. This is a so-called fake raid card. Just connect the drives to the SATA ports on the motherboard and use mdadm to assemble a software raid array from them. If you're not using parity raid you'll not notice the difference. Typically, only high-end cards are true hardware raid.
