Yeah, this is my main concern with moving from my cheap Linux server with no redundancy to ZFS RAID on OpenSolaris; I don't really want to have to pay twice as much to buy the 'enterprise' disks which appear to be exactly the same drives with a flag set in the firmware to limit read retries, but I also don't want to lose all my data because a sector fails and the drive hangs for a minute trying to relocate it, causing the file system to fall over.
So use the same cheap hardware you used on Linux.
I haven't found a definitive answer as to whether this will kill a ZFS RAID like it kills traditional hardware RAID or whether ZFS will recover after the drive stops attempting to relocate the sector. At least with a single drive setup the OS will eventually get an error response and the other files on the disk will be readable when I copy them over to a new drive.
A combination of ZFS and FMA on OpenSolaris means it will recover. Depending on many factors - not just the hard drive and its firmware - will depend on how long the time outs actually.
