I've got a handful of various low-end 3Ware cards scattered about in a few production boxes and I'm very happy with them. These are not "quasi-hardware-raid" like the onboard controllers. There is a cli management tool in the ports tree as well. You can probably still get the two port model for about $100.

The RAID5 code is not complete, it does not use nor maintain the parity, so it does actually only do RAID0. This is not wanted for a production release. === Take a look at e.g. the amr(4), aac(4) or arcmsr(4) manpages for a list of hardware that's closer to what you're looking for.

Promise FastTrak RAID 5 support ?
Hello, I've been googling for some time and I can't seem to find out whether the ata subsystem of FreeBSD supports the RAID5 feature of the Promise boards. Two boards seem interesting : (by Promise) FastTrak S150 SX4-M and FastTrak SX4100 (I haven't exactly seen the differences, though) from the ATA mkIII update commit log, it seems that the RAID support for Promises is fairly good, but even after a glimpse at the ata-raid src in cvsweb, I'm not sure of anything. Has any one a hint on a cost-effective, FreeBSD-supported RAID-5 SATA disk controller ?
