I'm on my second week of blue screens and hair pulling - all thanks to my new HIGHPOINT raid card. Their service is horrible. I'm getting one word useless responses from their service dept. I'm offering to pay them money to help me fix it and still nothing. I may fly to China to take a sh*t in their headquarters.
Furthermore, it turns out that these cards still rely on your cpu to move data around. Only more expensive cards do all their own processing (such as Promise cards).
Do not make the mistake I made. Lay out the coin for a good raid card.
