NVRAID's Reliability and Performance?

Question

I am planning to use 4 units of 500G Seagate SATA drive
(ST3500630AS) and I just got a new motherboard :
ASUS M2N32-SLI Deluxe, which has NVIDIA nForce 590 chipset with NVRAID feature. Can someone please give me some advise, if I should go with the NVRAID's Raid-5,
Is it reliable, and how good is it's performance ?
Or I should chose another vendor's dedicated RAID controller, if another vendor, which one has most reliable, performance o.k., and relatively lower cost.

Thanks for any input.

Answer 1

With drives that size on RAID-5, you will find performance not as you expect, as RAID5 required a lot of calculation, thats why you see dedicted cards on sell that cost more that your motherboard, as it needed onboard memory , on that number of drives, I guess you should look for a card with 128MB minimum, I normally use 3Ware cards for RAID5,
