Default Advanced RAID adapters

I'm looking to replace some parts of my server in april (when the E4300 drops in price), but I'm thinking of using a high quality raid card.

Reason is that I would like to use RAID 5 for some extra redundancy. I have tried that with an onboard (Nforce) raid, but it sucked in terms of speed, it couldn't even saturate a 100Mbps network.
I know onboard raid uses the CPU for most calculations, but that isn't much of a problem, cause it's not running anything CPU intensive. But the CPU usage was almost nothing, and it's speeds were too low.

Question is, will a good RAID card, with onboard processor (something like areca cards) be able to provide (much) better (read) speeds?

Not really interested in speding 1000$ if it can't, at least, go faster then 100Mbps. Then I'm better of with a cheap card.

I'm at +-150 MB/s read speed with an Areca 1210 RAID 5 setup ( 4x500GB Hitachi).

That's the cheapest Areca : +- € 300.

good, I had 4 500GB seagates (not the best in raid, I know) and they barely reached 50Mbps on the onboard nForce raid thingy.

I'm looking for more connections however (got a stacker with a max capacity of 20 disks if I push it.)

Areca has plenty versions for your needs

Or LSI is a good alternative...

Try a 3Ware 9650SE-4LPML with a multilane cable. Good for the airflow but very bad for your wallet
