I've got a Promise TX2300 SATA Raid controller that I use on my FreeBSD fileserver at home. It uses ataraid. I've set up a simple two-drive mirror. One of the drives has been sending me intermittent failure messages in the nightly emails for nearly a year - no more than one or two a month. Last night it finally croaked. The mirror broke, but it went into "degraded" mode and kept right on chugging along with no service interruption. Today I took down the system, replaced the bad drive, rebuilt the array using Promise's BIOS tools (since that's how I built it originally), and everything is back to normal. This was my first real drive failure with an inexpensive RAID card, and I'd always wondered if they could ease the pain of a hard drive failure. It looks like they can. I should add that before this, on another system, I had a RAID controller failure. A controller failure is a completely different scenario...
