HostRaid vs ZCR for RAID 10

Hi,
We are configuring a database server for RAID 10 and are wondering if there are any comparisons or benchmarks of the pros/cons of using the HostRaid built into the motherboards--Dell, Supermicro, etc... or using the ZCR card for Supermicro or a dedicated Adaptec or other card for the RAID. Are the benefits large enough to outweigh the costs of the extra equipment? or is HostRaid fine for RAID 10?

Thanks

What kind of drives?

I would invest in a real hardware RAID card if this database is work related.
Better performance.
3ware also still seems to make a true hardware RAID card.

Nice little rant on Host Raid cards.

Sweet.

If you do a Host Raid, the cpu will have to have to take time away from chewing on the database, to manage the disk drives.

Whether a hardware raid is worth it, depends on what kind of system specs you have, and how heavy the workload is going to be.

considering that we are looking at (2) 5100 series processors - 4 cores-- and the current config is running fine on a dual 2.4 xeon with raid 1, I would think that we have a lot of extra power available for use -- unless 64bit windows /sql 2005 is a LOT more cpu intensive than 2003/sql 2000

Not that I have heard of. Just be sure you can get all the drivers you need, first.

Sounds like  you will have no problem with cpu load, so either raid should work.

This is a nice place to start, to help decide which is better for you:

This is mostly Linux links, but there should be some good background info in there:
