Whats the cheapest way of using raid 5.

all the pci cards i've seen so far are scsi, and those drives cost a mint, i
would prefer sata.
Are there any motherboard that support it onboard?

thanks

Do a google search on "sata raid"

And the OP should be aware that the "cheap and cheerful" RAID solutions
(particularly common on consumer class motherboards) will be 0 or 1 or
0+1/10 and not RAID 5 capable, they'll also be software RAID. For full
hardware RAID (such as the sort built by 3WARE), you pay allot of money. I
have a 3ware 7500-4LP RAID card in my machine (which I bought second hand
via eBay) and although its capable of handling RAID 5, it performs faster in
RAID 10 mode - that will be the case with all RAID cards. The 3Ware website
is at www.3ware.com

Agreed. If the OP wants to do "proper" SATA hardware RAID, the 8000 or 9000
series is a good choice.

i had a feeling that it was software raid, but thought as there was a
physically controller on the motherboard this may not be the case.
Out of interest what kind of load does it put on the CPU in RAID 1?

thanks for the replies

Less than 3% according to 3Ware.

Using the 9500S-4LP and four 37GB 10K WD Raptors in RAID0, expect to see
140MB/sec.

sorry my mistake, i meant what was the cpu load using software raid not

There are NO motherboards that support RAID 5 SATA, or IDE for that matter.

On the order of 5-7% using a Barton at 2300MHz, IIRC.

Thanks a bunch guys

I just noticed that Raidmax power supply in your sig...
I wouldn't try running RAID 5 off of that, if that was your
intention as it's a liability already. It's certainly not a
true 420W power supply.

Thanks for the concern but i wouldn't dream of doing such a thing.
besides i've got two ata hdd and my motherboard only supports sata raid 0 &
1, lol.

The raidmax psu is "good" but no where need that good(i mean good as in it
does the job)
3.2v on the 3v
12.1 on 12v

I had just wanted to know how much that sort of thing would cost
