On-board SATA RAID question regarding drive failures

[AirGibson]

Have any of you experimented with onboard SATA RAID systems running a Raid 1 (mirrored) array? If so, will the system continue to operate if one of the drives fail, or does the failure cause problems (lock ups, require replacement before it will work again, etc...)?

In my experiences with uber-nice RAID controllers, the system continued running without missing a beat and simply notified me that one of the drives had failed. I was wondering if these onboard SATA RAID controllers were going to be as forgiving in the face of a drive failure.

I believe so. That is the point of having raid 1.

I've been told "some of the high end controllers, yes they keep on trucking, but the cheaper onboard ones dont let you". IOW, he's saying that your data is safe, but the system itself doesn't continue to operate untill the faulty drive is replaced / rebuilt.

I've heard it both ways, anyhow.
