Soft-RAID and Hard-RAID?

Hello!

I?m running some Mac OS X Servers with a Sonnet ATA-Card and two drives attached in RAID-1 configuration. (Soft-RAID that is included in Mac OS X).
After reading some really bad stories what?s happens when one drive of the soft-RAID fails, i want to switch to hard-RAID-1 solutions.

For myself I played around with the Soft-RAID in Mac OS X and was disapointed that I only see that one drive failed when I startup Disk Utility and select the RAID-Volume. No other warnings, NOTHING!!!

I expect to see a big warning at the login-screen that one drive failed!

After reconnecting the "failed" drive I had to rebuild the RAID by hand. Startup Disk Utility and rebuild it. But no data was lost.

I read some mails about drives in RAID-1 configs failing and than every data was lost !!!!
Why should I use a RAID-1?

What I have found are only ATA-Cards that support RAID-0 but not RAID-1.
Where can I get an ATA-Card that supports RAID-1?

Thanks, bye,
Christoph
