Isn't the benefit of ZFS that it will allow you to use even the most
unreliable risks and be able to inform you when they are attempting to
corrupt your data?
To me it sounds like he is a SOHO user; may not have a lot of funds to
go out and swap hardware on a whim like a company might.
ZFS in my opinion is well-suited for those without access to
continuously upgraded hardware and expensive fault-tolerant
hardware-based solutions. It is ideal for home installations where
people think their data is safe until the disk completely dies. I
don't know how many non-savvy people I have helped over the years who
has no data protection, and ZFS could offer them at least some
fault-tolerance and protection against corruption, and could help
notify them when it is time to shut off their computer and call
someone to come swap out their disk and move their data to a fresh
drive before it's completely failed...

Seriously, the best solution here is to discard any drive that is 3 years
(or more) old[1] and purchase two new SATA 500Gb drives. Setup the new
drives as a zfs mirror. Being a believer in diversity, I'd recommend the
following two products (one of each):
- Western Digital Caviar RE2 WD5000YS 500GB 7200 RPM 16MB Cache SATA
3.0Gb/s Hard Drive [2]
- Seagate Barracuda 7200.10 (Perpendicular Recording) ST3500630AS 500GB
7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive
Not being familiar with Macs - I'm not sure about your availability of
SATA ports on the motherboard.
[1] it continues to amaze me that many sites, large or small, don't have a
(written) policy for mechanical component replacement - whether disk
drives or fans.
