| 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 |
