HighPoint RocketRaid 454

[Tobias]

Hello, I know that this card has support in FreeBSD but I'm curious if 
anyone has used them under heavy load in a RAID-5 configuration.

We're thinking of equipping two of these cards with 8 120GB Hitachi drives 
and run it in an RAID-5 array for video material.

The usual data streams will likely be 2-3 streams at about 5-20MB/s 
(totally) and I know that a single drive will handle that, but I'm unsure 
if the HPT 454 is really stable in FreeBSD.

We'll be running this on a 4.8 installation.

Now to my questions...
Is the HPT 454 card & driver production stable?
Do you think that it will handle 60MB/s (read)?
Has anyone had a drive failure with this card and successfully replaced it 
while the system was running or am I placing my hopes too high?
